What are the most important things to do after installing Ubuntu 22.04 LTS? With the release of Ubuntu 22.04 LTS Jammy Jellyfish, Canonical yet again fulfills its promise of offering a safe, dependable, and resolute open-source OS for the edge, cloud, and IoT smart systems alike.

The introduction of Ubuntu 22.04 LTS offers tons of amazing features and tools for system developers, administrators, and end users. And to make your Ubuntu experience even better, you can enhance your security with a VPN app. To get Ubuntu VPNs, always consult the experts’ reviews first.

Installing a new copy on your system will provide you with a wonderful experience. Nonetheless, if you are a veteran user of Ubuntu and updating your older version to the latest one, your new ride might get a bit rocky in the start.

Here are 5 things you can do after upgrading Ubuntus’s OS version to get the most out of it:

5 Things To Do After Installing Ubuntu 22.04 LTS

As stated earlier, upgrading your Ubuntu version from an older version can lead to a few problems. While the things that may need a bit of ironing aren’t aplenty, they’ll get you frustrated, compelling you to fix them as early as possible.

Do the following things after you have updated Ubuntu to the latest 22.04 LTS Jammy Jellyfish version:

  • Erase old software and system files
  • Assess the AppImage compatibility
  • Check if your VPN subscription is still valid
  • Mend the Videos app
  • Install a Fresh Version of Mozilla Firefox

1. Get Rid of Previous Software from Your Linux System

In Ubuntu 22.04, many preinstalled apps have been removed. As a result, any technology on which the apps rely must be deleted from your device.

These requirements use expensive disc space and may be uninstalled using the auto-remove prompt from the gateway:

 sudo apt autoremove

When asked, enter your login, and press Y to authorize removal.

2. Assess the AppImage Compatibility

Some of the users have discovered and filed complaints about the AppImage application. AppImage files, including Flatpaks and Snaps, are platforms of independent applications. AppImages are not downloaded. They just execute instead, providing portability.

Many AppImages, though, do not appear to operate properly with Ubuntu 22.04 LTS. Perform the following command to increase the likelihood of them launching:

sudo apt install libfuse2

To give the AppImage the best possible chance of working, right-click the AppImage file with the issue and choose Permissions. Check the Allow running file in the application box.

If the issue continues, put up another AppImage file. If this helps, re-download the file that was giving you difficulties.

3. Check if your VPN Subscription is Still Valid

Many apps may demand updates after switching to Ubuntu 22.04 LTS, however, few are easier to perform than others.

The upgrade to Ubuntu 22.04 LTS causes a directory shift, rendering ExpressVPN inoperable. If you’ve ever tried to install ExpressVPN on Linux, you’ll know that it’s not an easy task.

To correct this, start a terminal to use ln command and to connect the following file paths:

sudo ln -s /usr/bin/resolvectl /usr/bin/systemd-resolve

This fix just needs to be applied once. You do not need to restart your computer—- ExpressVPN should just restart at this point.

4. Mend the Videos (Totem) Application

After updating to Ubuntu 22.04 LTS, there is a major issue with the Videos software (commonly known as Totem). This may occur with both Wayland and Xorg screen servers and it is not unique to either.

Totem should open and display a video file (of any type, including MP4 and MOV) when you double-click it. This, however, does not occur with the recent Ubuntu upgrade.

There are 2 viable solutions.

One solution is to just switch to another application. VLC Player is indeed a logical option.

Another option is that you delete the gstreamer1.0-vaapi file. GStreamer is a media platform that allows you to manage media files. This looks to be unnecessary in Ubuntu 22.04 LTS, and it surely slows down the Videos application.

To delete, use a terminal and type:

sudo apt remove gstreamer1.0-vaapi

When finished, your videos will appear in the Totem/Videos app immediately.

5. Install the Latest Version of Firefox

The update of Firefox is one of the most vexing issues with Ubuntu 22.04 LTS. It was pre-installed in previous versions in the same manner as other applications.

Mozilla Firefox is much more secure now that it supports Snap packages, executing within its own snap-managed firewall and auto-updating. However, this slows down the software.

Luckily, there is a method for restoring the previous Mozilla Firefox configuration.

First, delete the Snap edition of Firefox from the Terminal by using

sudo snap remove –purge firefox

You’ll have to include the Mozilla Team PPA file to get the “actual” Firefox. When this is done, you will have a site to download Firefox from. Enter again into the terminal

sudo add-apt-repository ppa:mozillateam/ppa

When prompted, enter your password.

Use apt to download Mozilla Firefox.

sudo apt install -t ‘o=LP-PPA-mozillateam’ firefox

Take note of the -t ‘o=LP-PPA-mozillateam’ option. This condition guarantees that the apt employs the PPA you selected previously as the installation’s provider.

After that, you may use the “actual” Firefox instead of the Snap file.

Avoid Update Issues

It’s a good practice to make sure that the new Firefox version isn’t overwritten by the Snap version. Because the PPA version has lesser importance, this can occur when the software automatically upgrades.

You can circumvent this by assigning your priorities to the PPA-installed Firefox.

Launch gedit in the terminal.

sudo gedit /etc/apt/preferences.d/mozillateamppa

Add the following to the new text file:

Package: firefox*

Pin: release o=LP-PPA-mozillateam

Pin-Priority: 501

Save and then close the file. Run the command:

sudo apt update

Firefox from the PPA is now the default version for future Ubuntu releases.

But if you would like to go back to Firefox’s Snap model:

  • Activate Software & Updates
  • Choose Other Software
  • Examine the Mozilla Group PPA that you added before.
  • Select Remove.
  • Type sudo apt update && sudo apt install firefox in a Terminal window.
  • After that, Snap-managed Firefox will be restored!
