Hi All:
I'm getting a printing error in an x2go instance that has worked for a long time, and am hoping to get some help. The error that shows up in the client side (windows) print window is:
CUPS-X2GO Local Printer /usr/lib/cups/backend/cups-x2go failed
The server where I'm running x2go ran out of disk space before a fix got done, and am wondering if that munged a key or set of files, as am guessing this is something to do with printing authentication (it's a single node x2go server and x2go printing).
I've tried re-installing the x2go printing (cups-x2go, x2goserver-printing). I've copied in a "cupsd.conf" from another working instance.
The /var/log/cups/error_log says:
W [11/Apr/2016:12:15:14 +0000] Please move "SystemGroup lpadmin" on line 3 of /etc/cups/cupsd.conf to the /etc/cups/cups-files.conf file; this will become an error in a future release.

I can remove all the x2go packages and reinstall, but am unsure if that will address the problem (have not yet tried "Please move "SystemGroup lpadmin" on line 3 of /etc/cups/cupsd.conf to the /etc/cups/cups-files.conf file" because printing is working in other x2go instances). Any help appreciated...
Thanks!
