Title:
  Removals keep removing dependencies if removal of a package fails

Status in apt package in Ubuntu:
  Fix Released
Status in apt source package in Disco:
  Won't Fix
Status in apt package in Debian:
  Fix Released

Bug description:
  [Impact]

  Assuming packages A and B, with A depending on B. A has a failing
  prerm script.

  Expected behavior:
  - A fails to be removed, A and B stay unchanged
  Actual behavior:
  - A fails to be removed
  - B is still removed

  This might crash their system (e.g. if A is systemd and B is
  libsystemd0).

  [Test case]
  See Impact. An automated version of the test case (test-apt-get-remove-depends) is included and run on autopkgtest.

  [Regression potential]
  We now abort earlier in removal failures, that might be harder to recover from or not, nobody really knows.
