I've issued the commands systemctl daemon-reload and systemctl restart cups.service

As X2Go developers, we don't have much impact on the CUPS systemd
service start file. That is owned by the CUPS software package.
However, we can tweak cups-x2go [1]. It would be nice if you could
experiment with that a little and move the "$ENV{TMPDIR}="/tmp";"
statement that is part of the script to the very top of the script
(after all the "use ...;" statements.
When done, remove your hack again (which brings back more security
into your CUPS daemon) and re-test cups-x2go. Let me know if that
works for you. If so, please send your patch.
Thanks, Mike
