Ok really strange, after running once with aa-complain, it seems to solve the problem.
In syslog I see this: golem4 kernel: [188942.996377] audit: type=1400 audit(1507148174.867:125): apparmor="ALLOWED" operation="open" profile="/usr/sbin/cupsd" name="/proc/20273/cmdline" pid=20273 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Before that I see entries that look like this: Oct 4 12:50:54 golem4 kernel: [151422.393607] audit: type=1400 audit(1507110654.087:74): apparmor="DENIED" operation="open" profile="/usr/sbin/cupsd" name="/proc/2399/cmdline" pid=2399 comm="cupsd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0 Oct 4 12:50:54 golem4 kernel: [151422.393706] cupsd[2399]: segfault at 0 ip 00007fb9ba1f7715 sp 00007ffce931b968 error 4 in libc-2.24.so[7fb9ba0aa000+1be000] Oct 4 12:50:54 golem4 systemd[1]: cups.service: Main process exited, code=dumped, status=11/SEGV Note it says apparmor="DENIED" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1706052 Title: cupsd crashes with SIGSEGV on ubuntu 17.04 on start To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1706052/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
