2022-11-29 04:08:21 Chris Deckard description ==================================================== I know the useradd command is discouraged, but I wanted to report the bug to make the maintainers of the package aware. Recently there was an update of Ubuntu's passwd which is sourced from shadow from version 4.8.1-1ubuntu5.20.04.2 to version 4.8.1-1ubuntu5.20.04.3 When using the useradd command, the /etc/skel directory with contents ==================================================== ls -lah /etc/skel total 60K drwxrwxrwx 10 root user 4.0K Nov 28 18:33 . drwxr-xr-x 155 root root 12K Nov 28 19:12 .. drwxrwxrwx 2 root user 4.0K Nov 28 18:23 .backgrounds -rwxrwxrwx 1 root user 220 Nov 28 18:23 .bash_logout -rwxrwxrwx 1 root user 3.7K Nov 28 18:23 .bashrc drwxrwxrwx 6 root user 4.0K Nov 28 18:23 .config drwxrwxrwx 3 root user 4.0K Nov 28 18:23 Desktop drwxrwxrwx 2 root user 4.0K Nov 28 18:30 .fonts_stuff drwxrwxrwx 2 root user 4.0K Nov 28 18:23 .icons -rwxrwxrwx 1 root user 765 Nov 28 18:23 .profile drwxrwxrwx 2 root root 4.0K Nov 28 18:32 testfolderempty drwxrwxrwx 3 root user 4.0K Nov 28 18:23 .themes drwxrwxrwx 14 root user 4.0K Nov 28 18:23 WinAte ==================================================== only copies in the one empty folder. ==================================================== ls -lah /home/user20 total 12K drwx------ 3 user20 user 4.0K Nov 28 19:12 . drwxr-xr-x 18 root root 4.0K Nov 28 19:12 .. drwx------ 2 user20 user 4.0K Nov 28 19:12 WinAte ls -lah /home/user20/WinAte/ total 8.0K drwx------ 2 user20 user 4.0K Nov 28 19:12 . drwx------ 3 user20 user 4.0K Nov 28 19:12 .. ==================================================== I noticed in the strace calls for useradd that the kernel is returning the correct count of directories, but the useradd is clearly not copying all of them. Below is the strace output. ==================================================== strace useradd -k /etc/skel -g 900 -m -s /bin/bash -p P@ssw0rd! -c User20 user20 execve("/usr/sbin/useradd",
