[Bug 1916250] Re: gir1.2-signon-2.0 needs to declare replace on older releases (Groovy2Hirsute)

[Rolf Leggewie]

Thank you for your comment, Robie.

I agree about Conflicts most likely not being required here.  I felt it
was conservative to add so as not to introduce a regression if both
packages are installed.  After some further looking into it, a
regression is unlikely.  The file in question is identical in both
packages, unchanged upstream for 8 years, so it's safe to "overwrite"
with the "newer" version: https://gitlab.com/accounts-sso/libsignon-
glib/-/tree/master/pygobject  So, in the end, the conservative thing to
do is to allow anyone with the need to install both packages at the same
time and do a Replaces only.

About the versioning, I also agree that in general it is a good idea to
be more permissive and limit restrictions by versioning them.  In this
case, in essence the package name is already the versioning.

Bottom line: Can you drop the Conflicts line in the patch but otherwise
upload as proposed here?

Title:
  gir1.2-signon-2.0 needs to declare replace on older releases
  (Groovy2Hirsute)

Status in libsignon-glib package in Ubuntu:
  New

Bug description:
  gir1.2-signon-1.0 from groovy
  gir1.2-signon-2.0 from hirsute

  above two packages ship the same file /usr/lib/python3/dist-
  packages/gi/overrides/Signon.py without specifying how to resolve the
  conflict.

  Unpacking gir1.2-signon-2.0:amd64 (2.1-3) ...
  dpkg: error processing archive /var/cache/apt/archives/gir1.2-signon-2.0_2.1-3_amd64.deb (--unpack):
   trying to overwrite '/usr/lib/python3/dist-packages/gi/overrides/Signon.py', which is also in package gir1.2-signon-1.0 1.14+17.04.20161117-0ubuntu5
  Errors were encountered while processing:
   /var/cache/apt/archives/gir1.2-signon-2.0_2.1-3_amd64.deb
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  Probably needs a conflicts/replaces dependency added to the newer
  hirsute package.
