*** This bug is a duplicate of bug 1780227 *** https://bugs.launchpad.net/bugs/1780227
On Container restart I found a bunch of unrelated apparmor denies that look like: [1220983.698955] audit: type=1400 audit(1535545118.043:8745): apparmor="DENIED" operation="mount" info="failed flags match" error=-13 profile="lxd-cpaelzer-cosmic-systemd_</var/lib/lxd>" name="/run/" pid=21102 comm="mount" flags="rw, nosuid, nodev, remount" That is LXD on the Host being denied to do things Further when restarting systemd-resolved I saw these: [1221051.971026] audit: type=1400 audit(1535545186.315:8854): apparmor="DENIED" operation="file_lock" profile="lxd-cpaelzer-cosmic-systemd_</var/lib/lxd>" pid=22329 comm="(resolved)" family="unix" sock_type="dgram" protocol=0 addr=none Knowing that I also realized that the broken systems all had no reboot for quite some time, but the repro KVMs are obviously new. With that in mind I found bug 1780227 sounds close enough I think. Rebooted the host to a newer kernel and e voila that is it. That said I'll make this a dup, but this is a rather "hard" impact. We should make known that Cosmic since today fails to work in containers prior to Kernels: - 4.4.0-134.160 - 4.15.0-33.36 Unfortunately the Guest-Container can enforce no dependencies onto the host kernel. I'll discuss potential extra communication in standup today. ** This bug has been marked a duplicate of bug 1780227 locking sockets broken due to missing AppArmor socket mediation patches -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1789627 Title: systemd-resolved of systemd 239 is failing in cosmic containers Status in systemd package in Ubuntu: New Bug description: Hi, a few hours ago I realized that some of my containers have no working dns resolution anymore. Usually I'd think I broke something in my host network, but I was suspicious s it hit me on my laptop and on a server at about the same time. After a while I found that in those containers I have: systemd-resolve --status Failed to get global data: Failed to activate service 'org.freedesktop.resolve1': timed out (service_start_timeout=25000ms) Later I found two more things leading me to some assumptions: 1. I had no resolv.conf so the service seems to have issues root@c:~# ll /etc/resolv.conf lrwxrwxrwx 1 root root 39 Aug 28 22:18 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf root@c:~# ll /run/systemd/resolve/stub-resolv.conf ls: cannot access '/run/systemd/resolve/stub-resolv.conf': No such file or directory 2. I realized this only affects cosmic container Bionic container on the same machine is ok (so Host network should be ok I think). I didn't realize at first as other cosmic's were ok, but those were the containers not updated yet and tonight there was a publish of https://launchpad.net/ubuntu/+source/systemd/239-7ubuntu4 Knowing that I checked logs and found: Aug 29 10:23:25 c systemd[158]: systemd-networkd.service: Failed to update dynamic user credentials: Permission denied Aug 29 10:23:25 c systemd[158]: systemd-networkd.service: Failed at step USER spawning /lib/systemd/systemd-networkd: Permission denied Aug 29 10:23:25 c systemd[1]: systemd-networkd.service: Main process exited, code=exited, status=217/USER Aug 29 10:23:25 c systemd[1]: systemd-networkd.service: Failed with result 'exit-code'.
