[Pkg-cups-devel] Bug#363226: cupsys: Bad $TMPDIR causes admin server-error-internal-error

[Andrew Schulman]

Package: cupsys
Version: 1.1.23-15
Severity: normal


>From the web interface, when I try to run "Configure Printer", I get
"Error: server-error-internal-error".  The error logs don't provide
any information about the cause of the trouble, even at LogLevel
debug2.

To make a long story short, I found that this problem is caused by the
following combination of events:

(1) root exports environment variable TMPDIR=/tmp/root
(2) root runs /etc/init.d/cupsys restart
(3) A non-root user (in the lpadmin group), who can't read or write
$TMPDIR, signs onto the web interface and tries to run "Configure
Printer"

If root unsets TMPDIR and restarts cupsd, the problem goes away.
