As it's coming up to the first anniversary of the bug, I thought I would mention that I too have run into it. I normally use Ubuntu 12.04 but I'm trying out Ubuntu 16.04, so my first reaction was that the user interface for CUPS must have changed.
However I got pointed to this page and succeeded with the above mentioned fix of changing line "ExecStart=/usr/bin/cupsd -l" to "ExecStart=/usr/bin/cupsd -f" in /lib/systemd/system/cups.service and then "systemctl daemon-reload" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1598300 Title: CUPS web interface stops responding after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1598300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
