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 .../ros-image-proc_1.16.0-3_amd64.deb ...
Unpacking ros-image-proc (1.16.0-3) ...
dpkg: error processing archive /var/cache/apt/archives/ros-image-proc_1.16.0-3_amd64.deb (--unpack):
trying to overwrite '/usr/share/image_proc/package.xml', which is also in package libimage-proc-dev:amd64 1.16.0-2
Errors were encountered while processing:
/var/cache/apt/archives/ros-image-proc_1.16.0-3_amd64.deb
cheers,
Andreas
