Top 14 Things to do After Installing Ubuntu 20.04 LTS

On April 23rd, 2020, the Canonical team released the much-anticipated Ubuntu 20.04  LTS (Focal Fossa)  release. The latest release takes over from its predecessor Ubuntu 18.04 LTS and ships with a new and sleek desktop theme, an improved overall look-and-feel, Linux kernel 5.4, ZFS file system support and tons of hardware improvements and software enhancements. Ubuntu 20.04 is a Long-Term Service (LTS) release, and as with any LTS release, it will be supported for 5 years until 2025.

After installing Ubuntu 20.04 LTS on your system, here are some of the top 14 things that you should consider doing before you fully start using your system.

1) Install Latest Package Updates

It’s always a good idea, after installing a new Linux system, to update the system packages and repositories. This helps you to start working with the latest system packages and security updates. Therefore, to refresh your system and update system packages, run the command:

pkumar@linuxtechi:~$ sudo apt update && sudo apt upgrade -y

2) Customize the appearance / look-and-feel 

Since the release of Ubuntu 18.10, the default theme for Ubuntu has always been the sleek and neat Yaru theme. This time around, the Canonical team amped up their efforts and decided to ship 3 variants of the Yaru theme complete with a set of polished icons. The variants of the Yaru theme are light, standard, and dark. By default, Ubuntu 20.04 LTS runs the standard version of the Yaru theme.


A switch to the dark theme gives you the appearance shown below:


Furthermore, Ubuntu 20.04 packs with additional background images that you can apply to give your wallpaper a splash of color and enhance its appearance.


Apart from the flexibility of switching between different themes and wallpaper options, users can play around with the dock settings and increase the size of icons.


3) Install GNOME tweak tool

GNOME tweaks, popularly referred to as the GNOME Tweak Tool, is a free customization tool that provides you with extended flexibility to further customize your GNOME desktop appearance, shell extensions,  windows settings, and Power settings to mention a few.

pkumar@linuxtechi:~$ sudo apt install gnome-tweak-tool -y


4) Install Media codecs to enable playing of MPEG4 & other media files

By default, Ubuntu 20.04 LTS, like other previous versions, doesn’t support playing media files such as MPEG4 and AVI. If you want to play such media files, you need to install the Ubuntu restricted extras package. This is a software package that comprises essential applications such as media codecs, Adobe flash & GStreamer. To install the Ubuntu restricted extras package, run the command below:

pkumar@linuxtechi:~$ sudo apt install ubuntu-restricted-extras -y

On the EULA screen, use the tab key to accept the terms and conditions of the EULA and hit ENTER on the ‘Ok’ option.


On the next screen, select ‘Yes’ to accept the license terms. Thereafter, the system will proceed to install the Ubuntu restricted extras package.


5)  Enable and Configure Firewall (ufw)

pkumar@linuxtechi:~$ sudo ufw status
Status: inactive

pkumar@linuxtechi:~$ sudo ufw enable

Firewall is active and enabled on system startup

6) Install Synaptic Package Manager

7) Configure your email client

Sure, you can access your emails via a web browser, but Linux, and more so Ubuntu 20.04, has made it easier through email clients such as the native Thunderbird email client.  You can easily follow through the instructions of adding your email account to Thunderbird email client which will allow you to receive and send emails. If Thunderbird doesn’t appeal to you, there are other options that you can install such as Evolution.

Creating a backup is one of the crucial tasks that any Linux user should keep in mind. Anything can go wrong when you least expect and when that happens, your system could suffer a fatal crash leading to loss of valuable data.

Timeshift is an open-source application that allows Linux users to create a system restore point from which they can revert to in the unfortunate event that something goes wrong.

Timeshift takes incremental snapshots of your entire operating system including your home folder, customizations, and system configurations. In case something goes wrong, you can restore your system to a point in time when the system was functioning perfectly.

You can install Timeshift by adding the Timeshift PPA as shown:

pkumar@linuxtechi:~$ sudo apt-add-repository -y ppa:teejee2008/ppa

Next, update your system to sync with Timeshift PPA.

pkumar@linuxtechi:~$ sudo apt update

And finally, install Timeshift using the command:

pkumar@linuxtechi:~$ sudo apt install timeshift -y
