Color emoji support is finally coming to Ubuntu.
Next April’s release of Ubuntu 18.04 LTS will be the first version of Ubuntu that can display color emoji in desktop apps, out of the box.
Ubuntu users will also be able to enter the glyphs in GTK apps using a searchable emoji picker.
Based on a recent bug report, all of the relevant packages needed to enable full support for color emoji in GTK apps will be in place for ‘Bionic Beaver’ in the coming days.
Ubuntu Emoji Support
I know what you’re thinking about this news — and I totally agree: this is a ground-breaking and earth shattering move that addresses the single most pressing and important concern with regards to Ubuntu’s future as a viable desktop operating system.
Alright, so emoji support in Ubuntu isn’t the sort of change many will willingly admit to caring about, but it is important.
Superfluous though they often seem, emoji are now an integral part of modern online communication for many, many users. An asinine glyph appearing at the end of a message can dramatically alter the meaning of text.
I thought Ubuntu could already do this?
We’ve covered various hacks that let you see and use color emoji on Ubuntu in various apps over the years — but few of those methods were perfect, catch-all solutions.
GTK apps on Ubuntu have been unable to render color emoji natively (even when a color emoji font is installed and working in other apps, like Firefox and Chrome).
It’s 2017; Ubuntu is well and truly behind the curve on support this rather basic feature. Fedora gained a neat emoji picker in 2016, and GNOME 3.26 comes with relevant support plumped in.
So it’s only right that Ubuntu devs put in the effort to catch up (lest it leave another bunch another bunch of LTS users marooned in the next decade, unable to see something as basic as brightly colored emoji).
Based on recent bug activity and package uploads all of the requisite packages are being put in to place. This will ensure everyone can see and use color emoji in Ubuntu 18.04 LTS in GTK apps out of the box — no hacks or extra packages required.
Thanks to GNOME developers most GTK apps, including Twitter app Corebird, the Polari IRC client, and the Web web browser, support an emoji picker option in valid text fields.
Ubuntu 18.04 LTS will use the open-source Noto Color Emoji font (the same emoji font used in recent versions of Android). This has the benefit of ensuring there’s (some) degree of consistency between platforms. Subtle variations exist in different emoji sets. This can, in some instances, alter the intended meaning of a message.
Hate emoji? Just remove the font
If the mere idea of having to glance at gleefully garish icons as you go about your business makes you itch, remember that you will be free to uninstall the emoji font from your system should you wish.
With every other major operating system out there able to display color emoji, and GNOME devs having done the hard work of adding support for them in native GTK apps, it’s only right that Ubuntu developers make use of the support.

Ubuntu 18.04 LTS is the current stable release of Canonical’s Linux operating system. It sports a lot of modern software thanks to backporting efforts. Despite this, users tend to get stuck on an aging version of the Linux kernel.
It’s not all that bad to be on Ubuntu LTS and stay stuck with an older release of the Linux kernel, as the developers do their best to port fixes and improvements down the line. Still, if you’re using 18.04 because of stability purposes, but would prefer to be using the latest and greatest Linux kernel (such as kernel 5,) you’ll be slightly annoyed. Luckily, because of the Linux community, it’s increasingly easy to use Linux kernel 5 on Ubuntu 18.04 LTS
Method 1 – With UKUU
The Ubuntu Kernel Upgrade Utility is the most straight-forward path to getting Linux use Linux kernel 5 on Ubuntu 18.04 LTS. To access the app, you’ll need to head over to our guide on how to install the UKUU application.
Once you’ve got the UKUU application working on Ubuntu, launch it by browsing for it in your application menu. Then, use the UKUU application to locate version 5 of the Linux kernel (the newest release available, preferably).
Select the version 5 kernel that you’d like to install on Ubuntu 18.04 LTS with the mouse to highlight it. After that, start the installation of the new kernel by clicking on the “Install” button to load it up on your system.
Let the UKUU app fully download and install version 5 of the Linux kernel on your Ubuntu Linux PC. When the installation process is complete, close the UKUU application and reboot Ubuntu 18.04 LTS. When it boots back up, you should be using version 5 of the Linux kernel.
Want to be sure that you’re running the absolute latest version of the kernel and that UKUU worked as intended? Launch a terminal window by pressing Ctrl + Alt + T or Ctrl + Shift + T and type:
Method 2 – From source
The Ubuntu Kernel Update Utility is a good tool, but given that it typically works with versions of the Linux kernel in development by Canonical, things can be a bit unstable. For a more stable solution, you can compile Linux yourself.
To start out the compilation process, you need to create a new configuration file. The quickest and most straight-forward way of going about this is by downloading an existing configuration file we have set up.
Note: don’t want to use our preset config file? Copy an existing file out of /boot and save it as “.config.”
After downloading the configuration file, it is time to download the latest release of the Linux kernel. As of writing this article, the version is 5.0.8.
Note: kernel versions are regularly posted on Kernel.org. If you want to update from 5.0.8 in the future, head there, download the new source and follow the instructions in this guide.
Extract the archive of the 5.0.8 kernel with the Tar command.
Move the new config file into the Linux code folder with the mv command.
Install the kernel build dependencies on Ubuntu, so that it is possible to compile and build it.
Run the GUI menu tool for the kernel with make menuconfig
In the menu app, leave everything at the defaults and use the arrow keys to select “Save.” Be sure to write the file to “.config.”
Exit the menu tool by highlighting “Exit.”
Once you’re out of the GUI menu editor, it’s time to use the lscpu command to figure out how many cores your PC has, to determine how many CPUs can be used to compile the kernel.
To figure out how many cores you have, run:
Keep that number in mind. Then, use make with the deb-pkg command to start the compilation for Ubuntu. Be sure to change “CORE-NUMBER” with the number that appears when you run the lscpu command.
Depending on how many CPU cores you have, your build will take a very long time. For best results, try to build on at least a dual-core CPU (2). When the building process is done, the compiler will output four ready to go DEB packages for your new kernel so that you may install them.
To install the newly compiled 5.0.8 Linux kernel, run the dpkg command.
Assuming dpkg installed successfully, reboot your Linux PC. When it comes back online, you should be running Ubuntu 18.04 LTS on Linux kernel version 5.
To confirm you are indeed running kernel 5 on Ubuntu 18.04 LTS, use the uname command.
OS X has emoji support inside terminal, and I’m a little jelly.
Emoji One Color SVGinOT Font brings emoji support to Ubuntu, but at the moment the terminal will only render monochrome emojis.
Is there a way to get these color beauties in gnome terminal?
5 Answers 5
I’m the creator of that font.
Sorry, there is not way to see SVGinOT (SVG-in-OpenType) color fonts in anything other than Gecko-based applications such as Firefox and Thunderbird right now. I made these fonts to solve the “chicken or the egg” problem: there were no color fonts and so no reason to support them. Now there are color fonts. Next steps: Probably a feature request on Launchpad?
Our wait is finally over guys! This is default terminal in
You may have to
In GNOME Terminal (it also works in any other application), use the following keyboard shortcut:
- Hit Control – Shift – E , then press Space .
- You should see the Emoji Choice popup where you can select your unicode character.
Tested on Ubuntu Cosmic (18.10).
Color Emojis are not currently supported. Apparently there is a patched WIP version of libcairo that allows rendering colored emojis but it isn’t stable yet.
Support for this will likely come down to something that needs to be implemented on a per-app or per-UI-lib (GTK, Qt etc) basis so it may take a while for some apps to support it even once the underlying OS libraries do.
UPDATE: The libcairo patch has made it’s way into mainstream repositories for most distros, they should now work natively by default if you have an up-to-date install, but you may need to modify your fontconfig to actually use them.

How to install the Development and build tools on Fedora 33?
If you are a developer you know that the database is an important element of the process. That’s why knowing the data and managing it quickly and comfortably becomes a priority. On the other hand, it is necessary to recognize that graphic clients are a great solution to this problem. With this in mind, this post will teach you how to install DBeaver on Ubuntu 20.4 / 18.04.
DBeaver is a client for database managers, which allows managing in a comfortable way the data and options of the database instance. It supports the main database applications, such as MySQL, MariaDB, PostgreSQL, Microsoft SQLServer, IBM DB2 or Oracle.
But not only is limited to database relationships but supports the handling MongoDB, Cassandra, and Redis. In other words, NoSQL database.
So, let’s install DBeaver.
The first step, to install DBeaver properly is to upgrade the system. So, open a terminal and run.
1.- Upgrade the system
The advantage of doing this is that you will have the security patches installed. With this, your system will be more stable.
DBeaver requires java to work. Its latest stable version adds support for Java 11, so you can use the steps outlined in our tutorial.
To make it even easier to install DBeaver it’s a good idea to do it from your repository. With this also, it will be easier to have it updated.
First, add the GPG key.
Next, add the repository.
2.- Add the DBeaver repository
Then, install DBeaver.
3. Install Dbeaver
Now we have to try DBeaver. To do this, first install some of the database handlers supported by the application. I will install MariaDB.
4.- Install MariaDB
Next, create a database and user for DBeaver.
5.- Creating the database
Next, launch it. Yo will see this.
Now, Create a new database connection. Go to File -> New. On DBeaver section, select Database Connection.
7.- Making a new connection
Select MariaDB. Next, set the connection settings.
8.- Setting the parameters of the new connection
After defining the connection parameters, if there is no driver installed, DBeaver will download it and show you something like this.
9.- Downloading the driver for MariaDB
Finally, you will see all the information about the connection.
10.- DBeaver working
Of course, having a large database, with lots of tables and data, you will understand the importance of DBeaver. For now, it won’t show any data.
Having a great tool to visualize the data and options of a database is very important if you are a developer. That’s why DBeaver is profiled as a pretty good tool focused on productivity. In addition, it has the advantage of being open source and supporting a large number of database handlers.
Please share this post with your friends. Happy new year.
I don’t know how often you type Emoji using your Linux desktop but none of the Ubuntu distros ships with that feature. The normal way to go about entering Emoji is to copy it and paste it into your desired location. It is thanks to IBUs-UniEmoji that you no longer need to do that.
IBus-UniEmoji is an Input Method that allows you to enter Unicode symbols and emoji by entering their name. It makes use of the IBus (Input Bus) framework – an input framework for Linux OS that provides full-featured and user-friendly input method UI.
The open source IBus-UniEmoji uses several sources against which it checks for emojis and returns them in order of their source. It also makes use of fuzzy search and so entering ‘egplnt‘ will return “eggplant“.
The GitHib page describes how IBus-UniEmoji carries out its searches and formats its results:
- If the character has an “emoji shortname” (provided by EmojiOne), the shortname will appear first in the result, surrounded by colons. A shortname is also a good indication that the candidate has an graphical representation, which will be replaced by an actual image on some clients (such as Twitter.com)
- If your search query matches an alias, the alias will be shown in square brackets
So, for example, searching for ‘eggplant‘ or ‘aubergine‘ will return:
And searching for ‘dog‘ (also an alias for ‘paw prints‘) will return:
Installation and Usage of IBus-UniEmoji in Linux
IBus-UniEmoji is still a small project and it seems to not have a .deb, snap, flatpak package, or even PPA for Ubuntu yet – but you can still install it by taking a few steps in your terminal:
- Firstly, download the archive from GitHub and extract it
- Open a new Terminal window and cd into the directory
- Run sudo make install
- Restart IBus using ibus restart
Secondly, add IBus-UniEmoji to your keyboard as an input source and assign a keyboard shortcut so that you can always easily switch between input methods like you would on a smartphone.
Take the following steps to add IBus-UniEmoji to your input source options:
- Go to ‘System Settings’ – > ‘Region & Language’
- Under ‘Input Source’ click ‘Add’
- Click ‘Other’ and select UniEmoji (in the ‘Other‘ category) in the list that follows
Lastly, repeat the above steps except that your native language is what you will add as an input type this time around. This is so that you can switch between typing with your native language and IBus-UniEmoji without the emoji palette always appearing. (That can be annoying.)
Now, you can switch to and from IBus-UniEmoji and smartly enter emoji to your texts while you type. Truly nifty! You can find out more about IBus-UniEmoji‘s usage on its GitHub page.
What do you think about IBus-UniEmoji? Have you used it before; or are you aware of an easier-to-use alternative? Let us know in the comments section below.

Packer is an open-source tool used to create virtual machine templates from a .json file.
To automatize the creation of templates in VMware vSphere ESX, there are two major approaches:
- Use theVMware-iso provider. This provider creates VMware VMs from an ISO file as a source. It currently supports building virtual machines on hosts running VMware Fusion for OS X, VMware Workstation for Linux & Windows, and VMware Player on Linux. It can also build machines directly on VMware vSphere Hypervisor using SSH as opposed to the vSphere API.
- Use thevSphere-iso provider. This provider, created originally by JetBrains, merged into the official Packer repository and released with Packer since version 1.5.2, builds VMs on VMware vSphere directly using vSphere API.
In this story, we will use vsphere-iso to create a Ubuntu 18.04.4 LTS (Bionic Beaver) template using Packer.
If you want to learn more about the process of building Windows Templates for vSphere with Packer, check this post → How to use Packer to build a Windows Server template for VMware vSphere
If you want to lea r n more about the process of building CentOS/RedHat Templates for vSphere with Packer, check this post → How to use Packer to build a CentOS template for VMware vSphere
If you want to learn more about the process of building Debian 10 Templates for vSphere with Packer, check this post → How to use Packer to Build a Debian 10 Template for VMware vSphere
2.Ubuntu 18.04 ISO → Ubuntu introduced the subiquity server installer in Ubuntu 18.04. The following code will not work on Ubuntu 18.04 Live or Daily Build versions. See point 6 to learn how to choose the right image.
3. VMware vSphere with vCenter → This example requires a VMware vCenter and will not work on the free VMware ESXi.
In our code, there are three files required to deploy a Ubuntu 18.04 Template in VMware using Packer:
- The Packer template → ubuntu18.json
- The Variables file → variables.json
- The preseeding file → preseed.cfg
We create a file called variables.json and add the following content.
This file defines variables to connect to VMware vCenter and create the virtual machine:
We create a file called ubuntu18.json and add the following content.
This file will connect to VMware vCenter and create the virtual machine.
We will break the file in several pieces to understand how it works.
Builders section: Establish the connection with the VMware vSphere.
Builders section: The communicator, uses ssh to communicate with the VMware virtual machine:
Builders section: virtual machine settings. The convert_to_template is used to convert the VMware Virtual Machine to a VMware Template.
Builders section: the final part of the Builders section is used to configure ISO images and floppy disks.
Here, we will define the ISO image: the Ubuntu iso file specified in the variables section.
Also, we will create a floppy and copy the preseed.cfg file inside it.
Then, we use the boot_command command to request Ubuntu to load the preseed.cfg file from the floppy disk and configure the server.
Provisioners section: the provisioner executes commands on the virtual machine using the shell provisioner. We can execute multiple provisioners here.
This file will configure the server on the boot time. We create a file called preseed.cfg and copy the content below.
Note: The preseed.cfg creates a user called kopicloud with password kopicloud. Update both preseed.cfg and variables.json files with your own credentials.
Ubuntu introduced the subiquity server installer in Ubuntu 18.04, so there are two major versions of Ubuntu:
- Live Build → ubuntu-18.04.x-live-server-amd64.iso
- Release Build → ubuntu-18.04.x-server-amd64.iso
There are a lot of ISOs on the page, so which one is the right one?
We open the page http://cdimage.ubuntu.com/releases/18.04/release/ in our browser and search for the file ended on server-amd64.iso. Right-click on the file and click on Copy link address option.
Update the iso_url variable on the variables.json with this link.
Then, we search for the checksum file SHA256SUMS.
In this tutorial, we will show you how to install Anaconda Python on Ubuntu 18.04, as well as some short tutorials on how to set up Anaconda environments.
Anaconda is a large and powerful platform of the Python and R programming languages. It provides a lot of tools that can be used in areas such as Jupiter Notebook, Pandas, and so on. Additionally, it is used for data processing, machine learning, and predictive analytics.
Anaconda provides a lot of popular python packages and package manager called ‘conda‘. Some of the popular anaconda packages are numpy, scipy, jypiter, nltk, etc… You will get all of these packages with anaconda instead of installing a plain version of python and using pip for managing and installing these packages.
Let’s get started with the installation.
Table of Contents
- For the purposes of this tutorial, we will use an Ubuntu 18.04 VPS.
- Full SSH root access or a user with sudo privileges is also required.
Step 1: Connect via SSH and Update
Connect to your server via SSH as the root user using the following command:
Remember to replace “ IP_ADDRESS ” and “ PORT_NUMBER ” with your server’s respective IP address and SSH port number.
Before starting with the installation, you will need to update your system packages to their latest versions. It’s easy to do, and it won’t take more than a few minutes.
You can do this by running the following command:
Once the updates are completed, we can move on to the next step.
Step 2: Install Anaconda
Before installing and downloading the Anaconda installer script, we should visit Anaconda Download page and check if there is a new version of Anaconda. The latest stable version of Anaconda at the time of this article being written is version 2019.03.
Now we will change to the tmp directory and here is where we will download the installation script. The download command for version 2019.03 has been written for you:
To verify the data integrity we will use the sha256sum command and verify the script checksum:
You should see an output similar to this:
We have to make sure that the printed output hash matches with the one at: Anaconda with Python 3 on 64-bit Linux, so that we can continue knowing that our copy of Anaconda is the correct one.
Step 3: Run the Install Script
Now we will start the Anaconda installation process by running the installation script:
You should see the following output:
We will press the [ENTER] key to continue the installation. The next step is to then agree to and approve the license terms:
Type yes, then press the [ENTER] key to submit your answer. Now we should choose the installation location.
We will choose the default path location /root/anaconda3. Press the [ENTER] key to continue with the installation. The installation will take some time – once it is completed, you will be prompted with the following output:
We will type yes so that we can use the conda command. You should be presented with the following output:
Next, we will activate the Anaconda installation and load the initial path which we added previously. To activate the Anaconda installer, run the following command:
We can verify the Anaconda installation by running the following command:
The following output should be given:
You now have a working copy of Anaconda on your Ubuntu 18.04 VPS. The next step can help you learn to use this new software.
Step 4: Creating an Anaconda Environment
Anaconda virtual environments help us to organize unique Python versions for each environment. This allows us to set up a different version of Python for each environment. Let’s create an environment using the latest version of Python.
Run the following command to create the environment (You can change ‘ virt_env ‘ to any name that you like, as well as the Python version):
Once it is created you can activate it with the following command:
If you want to deactivate it for any reason, just run this command:
That’s all there is to it – in this tutorial, we learned how to install Anaconda on Ubuntu 18.04, as well as how to create virtual environments. There are a lot more capabilities that Anaconda offers that we haven’t covered in this tutorial – this is why we suggest reading the documentation in order to be able to fulfill the server’s full potential.
Of course, you don’t have to install Anaconda Python on an Ubuntu 18.04 VPS if you use one of our Python VPS Hosting Solutions, in which case you can simply ask our expert Linux admins to install Anaconda on Ubuntu 18.04 for you. They are available 24×7 and will take care of your request immediately.

This brief tutorial shows students and new users how to use the su command on Ubuntu 18.04 LTS…
If you’re a student or new user looking for a Linux system to start learning on, the easiest place to start is Ubuntu Linux OS…. It’s a great Linux operating system for beginners..
Ubuntu is an open source Linux operating systems that runs on desktops, laptops, server and other devices…
During your introduction, you will find that Linux isn’t so different than Windows and other operating systems in so many ways, especially when it comes to using the system to get work done.…
Both Ubuntu and Windows systems allow you to be productive, easy to use, reliable and enable you to install and run thousands of programs from gaming to productivity suite software for individuals and businesses..
However, when you’re learning to use and understand Ubuntu Linux, you should also learn how to use the command line to terminal.. Most Linux users should be able to do some basic command line tasks.. This tutorial is going to show you how…..
When you’re ready to learn how to use the su commands, follow the guide below:
About su command:
The su command, which is short for substitute user or switch user, enables the current user to act as another user during the current login session… It changes the current user ID to that of a superuser or another user that you specified…
The syntax is the rule and format of how the su command can be used… These syntax options can be reordered, but a straight format must be followed.
Below is an example syntax of how to use the su command….
su [options] [LOGIN]
The command line options are switches or flags that determined how the commands are executed or controlled… they modify the behavior of the commands… they are separated by spaces and followed after the commands…
Below are some options of the su command:
|LOGIN…||Replace LOGIN….. with the username or login name you want to switch to.|
|-c, –command COMMAND
||Use the -c or –command to pass COMMAND to the invoked shell|
|-, -l, –login||Use the – or -l or –login to make the shell a login shell… This provides an environment similar to the user session|
|-s, –shell SHELL||Use the -s or –shell to specify a SHELL instead of the default in passwd|
|-h, –help||Use the -h or –help to display help message|
|Use the -m or -p or –preserve-environment to not reset environment variables, and
keep the same shell
|–help||Display a help message and exit.|
Below are some examples of how to run and use the su on Ubuntu Linux…
Simply run the su command to invoke it…
If you run the su command but don’t specify a login name, the command automatically switches to the superuser or root and run its interactive shell…
When you run the su command above, you’ll be prompted for the root password.. If the root password is authenticated and validated, the user running the command will automatically becomes root…
By default, authentication will fail when you want to change to root since the root account doesn’t have a password created with you install Ubuntu..
To add a password to the root account so you can authenticate, run the commands below
sudo passwd root
When you that, you’ll be prompted for your password.. then continue with asking to create and re-type a new password for the root account…
You’ll now be able to use the su command and temporary becomes root…
You can also run the su command with – or -l or –login.. This makes the mimic the shell environment similar to a real login, in this case the root..
To run another SHELL instead of the one defined by default in the passwd file, use the -s or –shell option … The below example will use the /usr/bin/zsh shell…
su -s /usr/bin/zsh
When you use su with -c or –command option, it causes the next argument to be treated as a command by most command interpreters…
su -c ls
The su command acts almost similar to the sudo command.. However, sudo command allows user to execute programs with root privileges…
On the other hand, the su command give temporary root shell to users… But users must know the root password.. This could be dangerous when sharing root password among users to gain root privileges…
In most cases, sudo is used..
When you run su with the –help option, you’ll see the help text below:
Congratulations! You’ve learned how to use the su command on Ubuntu…
