Recently there was an update of Ubuntu's passwd package which is

4.8.1-1ubuntu5.20.04.3
When using the useradd command, the /etc/skel directory with contents
below, an only copies in one empty folder.

[Touch-packages] [Bug 1998169] Re: useradd command does not copy all of /etc/skel
Further investigation made by the security team has identified that
focal and lower are affected because glibc in these versions does not
include the following commit:
https://sourceware.org/git/?p=glibc.git;a=commit;h=752dd17443e55a4535cb9e6baa4e550ede383540.
Therefore, jammy and kinetic, which have also been updated do not have
this problem. Focal, bionic, xenial and trusty, however, do, and
therefore, the updates will be reverted in order to remove the
regression.

[Touch-packages] [Bug 1998169] Re: useradd command does not copy all of /etc/skel
Initial analysis seems to indicate that this is happening due to a patch
added in the last update which is related to this commit:
https://github.com/shadow-
maint/shadow/commit/f3bdb28e57e5e38c1e89347976c7d61a181eec32. Checking
the manual for fchmodat in focal, it is possible to see the following:
AT_SYMLINK_NOFOLLOW
If pathname is a symbolic link, do not dereference it: instead operate
on the link itself. This flag is not currently implemented.
The flags seems to not be currently implemented.
No further changes to the code have been made by upstream.
More investigation will be made and the last update will possibly be
reverted.
