[Debian-med-packaging] Bug#948600: fastahack: missing Breaks+Replaces: libfastahack0 (<< 1.0.0+dfsg-4)

[Andreas Beckmann]

Package: fastahack
Version: 1.0.0+dfsg-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
'buster'.
It installed fine in 'buster', then the upgrade to 'bullseye' 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

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

  Preparing to unpack .../fastahack_1.0.0+dfsg-4_amd64.deb ...
  Unpacking fastahack (1.0.0+dfsg-4) ...
  dpkg: error processing archive /var/cache/apt/archives/fastahack_1.0.0+dfsg-4_amd64.deb (--unpack):
   trying to overwrite '/usr/share/man/man1/fastahack.1.gz', which is also in package libfastahack0 0.0+git20160702.bbc645f+dfsg-6
  Errors were encountered while processing:
   /var/cache/apt/archives/fastahack_1.0.0+dfsg-4_amd64.deb


cheers,

Andreas
