I got to launch it again, so I have finish with a cron job like
*/10 * * * * systemctl status cups.service|grep -q 'inactive (dead)' &&
systemctl start cups
but it is a dirty solution. I have no idea of what make it stop.
NB: I have seen problems related to apparmor, this machine has no apparmor
package.
+
+ [Impact]
+
+ If you want to use the CUPS web interface in Xenial and therefore set
+ "WebInterface Yes" in /etc/cups/cupsd.conf, CUPS could auto-shutdown
+ when it is idle and then an attempt to access http://localhost:631/ via
+ a web browser fails. People get confused as other access to CUPS
+
+ [Testcase]
+
+ Take a CUPS setup on Xenial with no shared print queues and CUPS only
+ listening on the domain socket. Activate the web interface via
+
+ cupsctl WebInterface=Yes
+
+ Now you are able to access the web interface via http://localhost:631/.
+ Wait for some minutes without accessing CUPS until the CUPS daemon shuts
+ down automatically. Try to open the web interface again and it will not
+ work.
+
+ With the fixed CUPS package CUPS will not auto-shutdown when the web
+ interface is activated.
+
+ [Regression Potential]
+
+ Low, as we are removing a simple distro patch to get back to the
+ original, upstream behavior.
