[Python-modules-team] Bug#960506: celery: missing Breaks+Replaces: python-celery-common (<< 4.4.2-3)

[Andreas Beckmann]

Package: celery
Version: 4.4.2-4
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'stable'.
It installed fine in 'stable', then the upgrade to 'sid' fails
because it tries to overwrite other packages files without declaring a
Breaks+Replaces relation.

See policy 7.6 at
https://www.debian.org/doc/debian-policy/ch-relationships.html#overwriting-files-and-replacing-packages-replaces

This test intentionally skipped 'testing' to find file overwrite
problems before packages migrate from 'unstable' to 'testing'.

>From the attached log (scroll to the bottom...):

  Preparing to unpack .../python-celery-common_4.2.1-3_all.deb ...
  Unpacking python-celery-common (4.2.1-3) ...
  dpkg: error processing archive /var/cache/apt/archives/python-celery-common_4.2.1-3_all.deb (--unpack):
   trying to overwrite '/usr/bin/celery', which is also in package celery 4.4.2-4
  Errors were encountered while processing:
   /var/cache/apt/archives/python-celery-common_4.2.1-3_all.deb


cheers,

Andreas
