Apart from the error messages and the exit code 100 the upgrade is
completed.

Libc6 could Pre-Depend: on libcrypt1, but this did not work well either
according to the changelog:

glibc (2.31-0ubuntu5) focal; urgency=medium

  * Move libcrypt1 back from pre-depends to depends; while this works fine
    on upgrades, it fails on new installations of libc6+libcrypt1 via apt,
    which is relevant for multiarch and therefore not viable.

glibc (2.31-0ubuntu4) focal; urgency=medium

  * debian/testsuite-xfail-debian.mk: mark as XFAIL various new tests which
    depend on a container setup which does not work correctly with Debian's
    multiarch-style layout.
    (https://sourceware.org/bugzilla/show_bug.cgi?id=25652)
  * Move libcrypt to pre-depends of libc, to ensure libraries possibly
    required by essential packages are always present on disk throughout an
    upgrade.
  * Install the architecture specific math-vector-fortran.h into the multiarch
    include dir. LP: #1861353.

APT could on the other hand could handle the issue with a warning/notice
only and return success and everything would be fine.

The good news is that with new images the problem will disappear because
if the native glibc packages are up to date installing the foreign one
succeeds without this warning.
