[R-pkg-team] Bug#970656: r-cran-isospecr: missing (unversioned) Breaks+Replaces: r-cran-isospec

[Andreas Beckmann]

Package: r-cran-isospecr
Version: 2.1.2-2
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 .../r-cran-isospecr_2.1.2-2_amd64.deb ...
  Unpacking r-cran-isospecr (2.1.2-2) ...
