`raw.lxc` is a "use at your own risk" option which you can use to directly configure things outside of LXD's control.
The upgrade from liblxc 2.0 to 3.0 came with backward incompatible config changes which indeed would hit those users directly using that key. We certainly don't want LXD to have anything to do with altering that configuration on upgrade but we did relax some of the checks such that you can "lxc config edit' the affected containers and set a working config before starting them again. ** Changed in: lxd (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851986 Title: LXD upgrade problem with existing container To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1851986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
