Hi,

so I was trying to print something after a long time of not printing anything.

I got the error message "Can't creeate temporary file" in http://localhost:631.

The reason was that /var/spool/cups/tmp was

drwxr-xr-x 2 root lp tmp

when it should have been

drwxrwxr-x 2 root lp tmp

otherwise HP PSC 2170 wouldn't print.

The cups service, in (gnu services cups) line 916, creates
/var/spool/cups as #o755. Sounds like it should be #o775.

Alternative URL:


I also ran into this problem and making the directory group-writable
fixed it.

After fixing that, it eventually auto-broke again after some time.
Permissions automatically reverted to the former ones.

Endless error loop :P
