But OTOH picking a random system - here a powerpc box and starting a cosmic container reproduces the same issue:

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'.
