Public bug reported:

When Apport is used with systemd-coredump, the CoreDump is zstd
compressed (instead of gzip). When filing Launchpad bugs, the zstd
compressed CoreDump is attached to the bug named CoreDump.gz (see bug
#2148535 for example). The file should be named CoreDump.zstd instead.
apport-retrace will complain about this coredump file, because it is not
valid gzip.
