5 Things to Do After Upgrading to Ubuntu 22.04 LTS

Ubuntu 22.04 LTS Jammy Jellyfish is the latest version of the popular open source operating system. Installing a fresh copy to a freshly wiped hard drive will give you a great computing experience.

However, if you’re upgrading from a previous version of Ubuntu, things can be a bit trickier at first.

Here are five things you need to do after upgrading to Ubuntu 22.04 LTS Jammy Jellyfish

Do these 5 things after upgrading to Ubuntu 22.04 LTS

After installing a new operating system, you will probably expect everything to work as good as it looks. Unfortunately, although Ubuntu 22.04 LTS works fine on fresh installs, upgrading from a previous Ubuntu release leads to some problems.

While the list of things to iron is short, they’re all annoying bugs that you’ll want to deal with sooner rather than later.

Once you have upgraded to Ubuntu 22.04 LTS Jammy Jellyfish, you will need:

  • Remove old software
  • Check AppImage support
  • Confirm your VPN still works
  • Edit Video App
  • Reinstall Mozilla Firefox (or switch browsers)

Below, I’ll explain each edit and fix it in more detail for you.

1. Remove old software from your Linux computer

Some pre-installed applications are deprecated in Ubuntu 22.04. Therefore, any software on which the application depends needs to be removed from your system. These dependencies take up valuable disk space and can be removed as follows from the terminal with autoremove request:

MAKE A VIDEO OF THE DAY
sudo apt autoremove

Enter your password when prompted, then Y to confirm removal.

2. AppImage Compatibility Check

Several users (including this user) have noticed and reported problems with the AppImage software.

Like Snaps and Flatpaks, AppImage files are platform agnostic packages. However, unlike Snaps and Flatpaks, AppImages (identified with the .AppImage file extension) are not installed. Instead, they simply run, ensuring portability.

However, some AppImages don’t seem to work properly with Ubuntu 22.04 LTS. To improve their chances of launching, run:

sudo apt install libfuse2

To ensure the best chance for AppImage to run, right click on the .AppImage file in question and select Permissions. Here, for sure Allow executing file as program is checked.

If the problem persists, try another AppImage file. If this works, re-download the one you’re having trouble with.

3. Check Your VPN Is Still Working

Various applications may require updates after upgrading to Ubuntu 22.04 LTS, but some of these are easier to do than others.

If you’ve installed NordVPN on Linux, you know it’s not a simple process. Upgrading to Ubuntu 22.04 LTS resulted in a directory change that made NordVPN unusable.

To fix this, open a terminal and use the ln command to link the following file paths:

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

This fix only needs to be run once. You don’t even need to reboot your system — NordVPN will simply work again from this point on.

4. Edit Video Application (Totem)

A major problem with the Videos app (also known as Totem) occurred after upgrading to Ubuntu 22.04 LTS. This can happen with Xorg and Wayland display servers and is not particular to both.

When a video file (in any format, including MOV and MP4) is double-clicked in Ubuntu 22.04, Totem will launch and play the file. However, after updating to the latest Ubuntu, this doesn’t happen.

There are two possible fixes for this problem.

One option is to simply switch to another app. VLC Player is an obvious alternative.

Another way is to remove the file gstreamer1.0-vaapi. GStreamer is a multimedia framework for processing media files. In Ubuntu 22.04 LTS this appears to be overkill and definitely hinders the Video app.


To delete, open a terminal and type

sudo apt remove gstreamer1.0-vaapi

Once done, your video files will open again in the Videos/Totem app.

5. Replace Snap Firefox with a faster version

One of the biggest attractions with Ubuntu 22.04 LTS is the change to the Firefox browser. In previous releases, it was pre-installed in the standard way, just like other apps.

With the move to support for Snap packages, Mozilla Firefox is more secure, runs in a fast managed sandbox, and updates automatically. However, this also makes the software run slower.

Fortunately, there is a way to go back to running Mozilla Firefox the old way.

Start by deleting the Snap version of Firefox in Terminal with

sudo snap remove 

To add the “real” Firefox, you need to add the Mozilla Teams PPA repository. Once this is added, you have a location to install Firefox. Again in terminal enter


sudo add-apt-repository ppa:mozillateam/ppa

Enter your password when prompted.

To install Mozilla Firefox with apt use

sudo apt install -t 'o=LP-PPA-mozillateam' firefox

Note the use of -t ‘o=LP-PPA-mozillateam’. This condition ensures that apt uses the PPA you added earlier as the source for the installation.

Once done, you can start using the “real” Firefox, instead of the Snap.

Avoid update problems

You should ensure that the new version of Firefox is not replaced by the Snap version. This can happen when the system automatically updates, because the PPA version has a lower priority than the Snap version.

You can avoid this by specifying a different priority for the Mozilla Firefox installed PPA

In terminal, open gedit

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

In the blank text file, add the following:

Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 501

Save, then exit the file. In the terminal, run

sudo apt update

Firefox installed PPA will now be the major version for the next Ubuntu updates.

And if you want to revert back to Firefox’s Snap version:

  1. Open Upgrade software
  2. Selection Other software
  3. Check the Mozilla team PPA you added earlier
  4. Click Eraser
  5. Open a terminal and enter sudo apt update && sudo apt install firefox

Then Mozilla Firefox managed by Snap will be reinstalled!

Enjoy Your Upgraded Ubuntu 22.04 LTS Jammy Jellyfish PC

If you’re lucky, you won’t have to do all 5 of these things. But if any of the above problems occur, the provided steps should resolve them.

In most cases, however, you’ll almost certainly want to replace Mozilla Firefox with the faster launch version you’re used to. It’s unfortunate that the Snap version has its cons for now, but perhaps that’s something that will be resolved with time.
