LXDE launch error

LXDE shows "Failed to close file descriptor for child process" error

[Tiryoh]

Adding --security-opt seccomp=unconfined flag while launching docker container solved the problem on Docker version 20.10.17 + Ubuntu 20.04.

If anyone came across the same problem, a workaround is to run the container with the flag --security-opt seccomp=unconfined.
There are security implications, more details here.

linuxserver/docker-digikam#22 (comment)

The problem is caused by a seccomp policy and a glibc >= 2.34 update (moby/moby#42681 (comment)) that returns an EPERM (operation not permitted) insted of ENOSYS (function not implemented).
