ProFTP stopped working

For some reason, ProFTP stopped working. When I tried to start it again, I got the error:

Code:

Starting proftpd:  - no such group 'nobody'
 - Fatal: Group: Unknown group 'nobody' on line 27 of '/etc/proftpd.conf'

Thanks in advance for any help you can offer!

 

That file is empty. How should it look?

 

It is a very important file, check it in your backups and restore it. It is as important as /etc/passwd and /etc/shadow

Maybe you have a copy in /etc/group~, /etc/group-, etc.

A sample of my /etc/group:

Code:

Holy crap, how did that get deleted? It looks like there was a backup called "group-" so I restored it, and ProFTP works now.
