[Bug 1965960] [NEW] apt installs snap packages

[ts]

Public bug reported:

$ lsb_release -rd
Description:	Ubuntu Jammy Jellyfish (development branch)
Release:	22.04

$ apt-cache policy apt
apt:
  Installed: 2.4.1
  Candidate: 2.4.1
  Version table:
 *** 2.4.1 500
        500 http://de.archive.ubuntu.com/ubuntu jammy/main amd64 Packages
        100 /var/lib/dpkg/status


3) I expected to dist-upgrade my system, running apt-get dist-upgrade

4) apt tried to install firefox from snap. I naturally aborted the upgrade, if I want a snap package I install it with snap, I use apt to install debian/apt packages.
Aborting the install essentially broke my system. Trying to repair it, and installing firefox using apt again, hence getting force-fed the snap of firefox, broke my install, too, as the snap cannot access my firefox configuration files (for good reasons).
It took me half a day to repair the system and switch to a PPA to keep the system (and Ubuntu with its intended processes - apt for deb, snap for snap, probably flatpaks and whatever for other stuff  - for that matter) running.

In summary: We know you love snap. We use snap for certain purposes, and apt for others. Please don't force your love for snap on us, snaps constantly break long-running systems and require careful introduction.
 
The proper solution could have been to stop supporting firefox from apt, so we have to consciously deal with the situation - without getting our systems broken.

Thanks ❤️
