[Debian-med-packaging] Bug#876130: libcamp-dev: fails to upgrade from 'stable' to 'sid' - trying to overwrite /usr/include/camp/args.hpp

[Andreas Beckmann]

Package: libcamp-dev
Version: 0.8.1-1
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#s-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...):

  Selecting previously unselected package libcamp-dev:amd64.
  Preparing to unpack .../libcamp-dev_0.8.1-1_amd64.deb ...
  Unpacking libcamp-dev:amd64 (0.8.1-1) ...
  dpkg: error processing archive /var/cache/apt/archives/libcamp-dev_0.8.1-1_amd64.deb (--unpack):
   trying to overwrite '/usr/include/camp/args.hpp', which is also in package libcamp0.7-dev 0.7.1.3-1
  Errors were encountered while processing:
   /var/cache/apt/archives/libcamp-dev_0.8.1-1_amd64.deb


cheers,

Andreas
