Hi,

during a test with piuparts I noticed your package fails to upgrade from
'testing'.
It installed fine in 'testing', 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

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

  Preparing to unpack .../libcpu-features-dev_0.6.0-1+b1_amd64.deb ...
  Unpacking libcpu-features-dev (0.6.0-1+b1) ...
  dpkg: error processing archive 
/var/cache/apt/archives/libcpu-features-dev_0.6.0-1+b1_amd64.deb (--unpack):
   trying to overwrite '/usr/include/cpu_features/cpu_features_cache_info.h', 
which is also in package libvolk2-dev:amd64 2.4.1-1
  Errors were encountered while processing:
   /var/cache/apt/archives/libcpu-features-dev_0.6.0-1+b1_amd64.deb
 
src:volk seems to use an embedded copy of libcpu-features-dev and ships it
in libvolk2-dev. I've requested that to be dropped in #978096, but as long
as this has not happened the version libcpu-features-dev should use in the
to-be-added Breaks+Replaces is only a guess.


cheers,

Andreas
