5 packages from scotch have an undeclared file conflict. This may result
in an unpack error from dpkg.

The files
 * /usr/lib/x86_64-linux-gnu/libptscotcherr.so
 * /usr/lib/x86_64-linux-gnu/libptscotcherrexit.so
are contained in the packages
 * libptscotch-dev
   * 6.1.0-2 as present in bullseye
   * 7.0.3-2 as present in bookworm
   * 7.0.7-1 as present in trixie|unstable
 * libptscotcherr-dev/7.0.8-1exp5 as present in experimental

The files
 * /usr/lib/x86_64-linux-gnu/libscotcherr.so
 * /usr/lib/x86_64-linux-gnu/libscotcherrexit.so
are contained in the packages
 * libscotch-dev
   * 6.1.0-2 as present in bullseye
   * 7.0.3-2 as present in bookworm
   * 7.0.7-1 as present in trixie|unstable
 * libscotcherr-dev/7.0.8-1exp5 as present in experimental

The files
 * /usr/lib/x86_64-linux-gnu/libscotchmetisv3.so
 * /usr/lib/x86_64-linux-gnu/libscotchmetisv5.so
are contained in the packages
 * libscotch-dev
   * 7.0.3-2 as present in bookworm
   * 7.0.7-1 as present in trixie|unstable
 * libscotchmetis-dev/7.0.8-1exp5 as present in experimental

The file /usr/lib/x86_64-linux-gnu/libptscotchparmetisv3.so is contained
in the packages
 * libptscotch-dev
   * 7.0.3-2 as present in bookworm
   * 7.0.7-1 as present in trixie|unstable
 * libscotchparmetis-dev/7.0.8-1exp5 as present in experimental

The file /usr/bin/gmap is contained in the packages
 * gmap
   * 2021-02-22+ds-1 as present in bullseye
   * 2021-12-17+ds-3 as present in bookworm
   * 2024-11-20+ds-2 as present in trixie|unstable
 * scotch/7.0.8-1exp5 as present in experimental

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.
