While upgrading a Debian 10 (Buster) LXC container to the current stable Debian 11 (Bullseye), the dist-upgrade process failed unexpectedly with the following error:

E: Sub-process /usr/bin/dpkg returned an error code (1)

All subsequent trials to continue the dist-upgrade failed.

This is the first time I personally ran into that specific error, but luckily I am not the first one to encounter this one. On StackExchange another user ran into the same Systemd related error and the solution is basically to remove the existing seccomp libraries (which cause the conflict):

root@debian:~# mv /lib/x86_64-linux-gnu/libseccomp.so.2* /tmp/

The distribution upgrade was then able to continue and finished correctly:
