Problem seems to be in Ubuntu packaging, as this fixes problem. 1) copy all containers to another LXD machine
2) do fresh Bionic install 3) copy all containers back At this point all problems resolve, so some sort of packaging problem in the Artful to Bionic upgrade. ** Summary changed: - /etc/netplan/50-cloud-init.yaml fails silently with no dhcp address assigned + Artful to Bionic upgrade kills all LXD container networking -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1768118 Title: Artful to Bionic upgrade kills all LXD container networking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1768118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
