[Bug 1999308] Re: Snap keeps uninstalling apt Firefox, and reinstalling snap Firefox

[Sebastien Bacher]

I'm not misunderstanding the situation

$ dpkg --compare-versions 1:1snap1-0ubuntu3 gt 113.0.2+build1-0ubuntu0.23.04.1~mt1; echo $?
0

in the dpkg sense the Ubuntu archive package version is newer than the
ppa one due to the epoch, apt is applying the standard logic of
replacing a deb package by a newer revision when available, it's the way
deb management is working.

I understand the issue your problem, you would like the firefox deb from
the ppa to not be replaced by the Ubuntu archive snap installer. For
that to work you need to use apt pinning to force the ppa to take
precedence over the Ubuntu archive version despite having a lower deb
revision, which has been suggested in the bug history.

The other option is to install firefox using the upstream tarball
instead of using a deb.
