systemd-sysusers.service Unit fails to start on a VPS

I am trying to troubleshoot my systemd-sysusers.service but I don't know where to start. First off a bit of background this is running Debian 10 on a VPS which uses Solaris VM among other technology

The unit is failing to start due to

? systemd-sysusers.service - Create System Users

The fact is that if I check sudo vi /etc/gshadow I just get a line regarding to cdrom

cdrom:*::debianuser

But Despite that I don't really have a clue on how to continue

systemd-sysusers expects the /etc/passwd & /etc/shadow, and similarly /etc/group & /etc/gshadow, files to be in sync with each other. If a group is missing, then it should be missing from both of those files. So when sysusers is adding a group that "doesn't exist" but finds it already present in /etc/gshadow, it reports this as an error.

Either manually add the group with groupadd so that it exists in both files, or manually remove it from /etc/gshadow so that systemd-sysusers will be able to properly re-add it, or use grpck to automatically fix all inconsistencies across both files.
