Attached is `journalctl -u avahi-daemon --boot -0 > avahi- journalctl.txt`.
I find lines "Host name conflict, retrying with daniel-desktop3-2" and "Detected another IPv4 mDNS stack running on this host" strange. They didn't happen last boot. I left `/etc/systemd/resolved.conf` at `#MulticastDNS=no`, and don't remember installing "another IPv4 MDNS stack". I used Docker today before the suspend. I exited all containers before the suspend. I started one container some time after the resume and it's running as of the time of writing, so it probably didn't affect anything despite lines mentioning its `veth`. ** Attachment added: "avahi-journalctl.txt" https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/2109419/+attachment/5874450/+files/avahi-journalctl.txt -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/2109419 Title: mDNS required avahi-daemon.service restart after resume Status in avahi package in Ubuntu: New Bug description: After suspending and resuming my desktop, my tablet could not resolve its hostname over mDNS. `getent hosts daniel-desktop3.local` has no output.
