Your system OS (Linux Lite 5.x) is based on Ubuntu Focal.
A repository for a mullvad application has been added to your system.
It appears that mullvad doesn't offer a version of their application which is compatible with Focal.
This is stopping the update/upgrade process from running.
You need to remove any elements of the mullvad application by reversing the instructions you followed when installing.
As part of this ensure that the mullvad repository is deleted from your system.

This should allow the update/upgrade process to run again.

Thanks.
I can see where I have gone wrong, but not how to reverse it.

The instructions I followed to (re)install Mullvad were:

# Download the Mullvad signing key
sudo curl -fsSLo /usr/share/keyrings/mullvad-keyring.asc https://repository.mullvad.net/deb/mullvad-keyring.asc

# Add the Mullvad repository server to apt
echo "deb [signed-by=/usr/share/keyrings/mullvad-keyring.asc arch=$( dpkg --print-architecture )] https://repository.mullvad.net/deb/stable $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/mullvad.list

# Install the package
sudo apt update
sudo apt install mullvad-vpn


Can you tell me how to reverse this?

Thanks

Thanks

You are welcome.

Those commands will have copied a mullvad keyring from the Internet into your /usr/share/keyrings directory and added a file called mullvad.list into /etc/apt/sources.list.d/ using priviledged access.

Open a terminal (Ctrl, Alt, T) and identify the 'mullvad' additions with

Code:

ls -l /usr/share/keyrings/

Code:

ls -l /etc/apt/sources.list.d/

Once you are happy you've identified the additions, you can delete them with these commands.
You will be modifying system critical locations so will need to enter your password.
Take care to only delete (rm) the specific files that were added by the mullvad install.

Code:

sudo rm /usr/share/keyrings/mullvad-keyring.asc

Code:

sudo rm /etc/apt/sources.list.d/mullvad.list

It is assumed the both the commands following "# Install the package" will have failed.
Provided they failed, there will be nothing to undo.
Let us know if those commands did anything other than report errors.

Once you've done tidying try running an update/upgrade sequence to ensure that completes.

That worked perfectly.

Thanks again. This is fantastic help.
