In this article, I present to you with 10 important things you might need to set up after you install Ubuntu 20.04 LTS (as it is the latest Long Term Support released). The lists are as follows.

Check & Update Available Packages

Checking for updates is the first thing to do after installing Ubuntu and you need to keep checking for updates from time to time. In the updates, there might be new security patches that may increase security as well as updates for the installed application.

To check the updates you should open a software updater from the show application which will automatically check for updates for you. Then click on install if there are any updates.

Update packages

You can also update the system using the command, you just need to execute the following command.

$ sudo apt update && sudo apt full-upgrade
Install Media Codecs

The initial installation of Ubuntu isn't compatible with any of the most common audio and video files like AVI, MP3, MPEG4, etc. You need to install media codecs manually for it using the ubuntu-restricted-extras meta-package. To install execute:

Install GNOME Tweak Tool

GNOME tweak is a tool for configuring the functionality and graphical interface of the desktop. It was designed for the GNOME shell but also used for easy customization of the desktop. You can install it using the command mentioned below.

Enable Firewall

As we all know what actually the firewall does, in Ubuntu UFW is the built-in and most reliable firewall. Initially, it was disabled by default so we need to manually enable it using the ufw command.

$ sudo ufw enable

Install Your Favorite Web Browser

By default, Mozilla Firefox is installed in Ubuntu which is a feature-rich and lightweight browser. Ubuntu supports various browsers like chrome, opera, etc. You can download and install the browser from the respective official sites. I prefer chrome more than any other browser so I will be installing it.

Install VLC

VLC is one of the popular media players which supports almost all types of modern media files. It is the simple and most widely used media player which supports both video and audio files such as MP3, AAC, DV Audio, MP4, FLV, etc. You can install it from the snap store using the snap command as it is distributed as a snapcraft.

Install Additional Archive Utilities

Tar, zip and unzip archive utilities are pre-installed in Ubuntu. In Linux distro, tar archive is mostly preferable for files and document sharing. If you want your system to support other file archivers you need to install it manually. Some of the archivers were rar, unrar, p7zip-full, and p7zip-rar.

$ sudo apt install rar unrar p7zip-full p7zip-rar

Set Up Livepatch

Setting up Livepatch will help you to keep your system secure as it applies the critical kernel patches as well as security patches without restarting the system. You need to create an Ubuntu account in order to activate this service and it is limited to only 3 devices. To activate it go to show application then, search for Livepatch and open it. Click on sign in and sign in to your Ubuntu account in order to activate it.
