CUPS broken - RESOLVED

[todd pitts]

The problem was simple (although very hard to diagnose).  There must be a world readable subdirectory called tmp in /var/spool/cups.  If this is not there you can't configure the printer options via the web interface (you get a completely meaningless server-error-internal-error message).  Also, there are NO indications in /var/log/cups/error_log that this is the problem - even on debug2.  I suggest that an appropriate error message be added to the debug logs and a comment be put in the docs referencing both web-interface failure to configure and the lpoptions -p printername -l return of "lpoptions: printername has no PPD file!" so the folks can actually use all of the other fine work that has been done on CUPS.
