As explained before, the behavior here is intended and not a bug. @Jan You are free to configure unattended-upgrades to install from the PPA or add negative pins for the Ubuntu (and UbuntuESM archives, if enabled) for src:firefox to prevent the snap from being installed.

I stand by what I said. If you don't want firefox from the official repository, pin it down. You'll want Package: src:firefox Pin: release o=Ubuntu Pin-Priority: -1 Package: src:firefox Pin: release o=UbuntuESM Pin-Priority: -1 Of course if you install multiple packages like that you need to list them all in the package line. This is noticably different from pinning up the PPA and again there is no easy way out here, the behaviour as is is what is generally needed. Adding the Debian repository is *NOT* supported. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2033646 Title: unattended-upgrade ignores apt-pinning to not-allowed origins To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/2033646/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
