Bug#874418: libdislocker0.7: fails to upgrade from 'stretch' - trying to overwrite /usr/lib/libdislocker.so

[Andreas Beckmann]

Package: libdislocker0.7
Version: 0.7.1-2
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
'stretch'.
It installed fine in 'stretch', 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

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

  Selecting previously unselected package libdislocker0.7.
  Preparing to unpack .../libdislocker0.7_0.7.1-2_amd64.deb ...
  Unpacking libdislocker0.7 (0.7.1-2) ...
  dpkg: error processing archive /var/cache/apt/archives/libdislocker0.7_0.7.1-2_amd64.deb (--unpack):
   trying to overwrite '/usr/lib/libdislocker.so', which is also in package libdislocker0.6 0.6.1-7
  Errors were encountered while processing:
   /var/cache/apt/archives/libdislocker0.7_0.7.1-2_amd64.deb

Why is this .so link in the shared library package and not in
the -dev package?

And please get rid of the insane idea of a libdislocker0.6
transitional package in sid.


cheers,

Andreas
