Bug#813080: linux-perf-4.4: fails to upgrade from 'sid' - trying to overwrite /usr/share/perf-core/strace/groups/file

[Andreas Beckmann <anbe@debian.org>]

Package: linux-perf-4.4
Version: 4.4-1~exp2
Severity: serious
User: debian-qa@lists.debian.org
Usertags: piuparts

Hi,

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

See policy 7.6 at
