fotocx has an undeclared file conflict.  This may result in an unpack
error from dpkg.

The files
 * /usr/share/applications/fotocx.desktop
 * /usr/share/man/man1/fotocx.1.gz
 * /usr/share/metainfo/kornelix.fotocx.metainfo.xml
are contained in the packages
 * fotocx/26.7-1 as present in unstable
 * fotoxx-common/24.70-1 as present in trixie

These packages can be unpacked concurrently, because there is no
relevant Replaces or Conflicts relation.  Attempting to unpack these
packages concurrently results in an unpack error from dpkg, because none
of the packages installs a diversion for the affected files.

Kind regards
