Package: cups-daemon
Version: 2.2.10-6+deb10u2
Severity: important
Dear Maintainer,
systemd creates /run/cups/cups.sock on boot and as soon as anything
connects to it (by e.g. lpstat), cupsd -l starts as expected. There are
no shared printers on the system and the web interface is not running,
so cupsd will eventually exit. When it does, I find it will unlink
/run/cups/cups.sock (seen by strace on the running cupsd process), which
causes subsequent invocations of lpstat to fail with "Bad file descriptor".
cupsd did not remove the socket in Stretch, but in Buster it does.
