apt: Instructions do not work for Debian Trixie

[simonhammes]

Is it a bug?

• [X] I know this is an issue with the app, and contacting Mullvad support is not relevant.

I have checked if others have reported this already

• [X] I have checked the issue tracker to see if others have reported similar issues.

Current Behavior

https://mullvad.net/en/download/vpn/linux contains the following snippet:

# 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

Running sudo apt update afterwards causes the following error:

E: The repository 'https://repository.mullvad.net/deb/stable trixie Release' does not have a Release file.

Expected Behavior

sudo apt update runs successfully

Steps to Reproduce

1. Use Debian Trixie
2. Add the signing key: sudo curl -fsSLo /usr/share/keyrings/mullvad-keyring.asc https://repository.mullvad.net/deb/mullvad-keyring.asc
3. Add the repository: 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
4. sudo apt update
