Debian Migration Guide

The structure of our Debian repository has changed. https://deb.librewolf.net has been replaced by https://repo.librewolf.net. If you previously used the old repository, please run the following commands in a terminal to move to the new repository and continue to receive updates.

Only follow these steps if you installed LibreWolf through APT on a Debian-like distro. If you installed LibreWolf using Flatpak (often just called something like "Software Center"), or by other means, you do not need to follow these steps, as that could result in errors or you having LibreWolf installed two times.

1. Remove the old repository from your PC

sudo rm -f \
  /etc/apt/sources.list.d/librewolf.sources \
  /etc/apt/keyrings/librewolf.gpg \
  /etc/apt/preferences.d/librewolf.pref \
  /etc/apt/sources.list.d/librewolf.list \
  /etc/apt/trusted.gpg.d/librewolf.gpg

2. Add the new repository to your PC

sudo apt update && sudo apt install extrepo -y

sudo extrepo enable librewolf

sudo apt --allow-releaseinfo-change update

3. Update LibreWolf (optional)

sudo apt upgrade librewolf -y

FAQ

Why is this necessary?

Our build process has fundamentally changed. We are now offering a single LibreWolf .deb for all Debian-based distributions instead of building for each distro separately. Our old repository could not account for that change. In addition, we used this opportunity to switch to a different GPG key.

What is extrepo?

Extrepo is an official Debian tool to more easily manage external repositories. It does not ship with every Debian distribution by default, so we also include instructions to install extrepo itself.

Can I continue using the old repository?

No, it will not be provided with updated versions anymore and should already contain an expired signature right now.

How do I know whether I am still using the old repository?

The new repository will be registered at /etc/apt/sources.list.d/extrepo_librewolf.sources, so if that is a valid existing file on your system, you are already using the new repository. To check that, you can run:

ls /etc/apt/sources.list.d/extrepo_librewolf.sources

If this does not result in an error like ls: cannot access '/etc/apt/sources.list.d/extrepo_librewolf.sources': No such file or directory, you are already using the new repository. If you are using the old repository, you will probably also see an error like this when trying to run sudo apt update:

Get:4 https://deb.librewolf.net bookworm InRelease [16.7 kB]
