The DPKG error is reasonably clear: - xenial9: Failed to load raw.lxc
That indicates you have a container (or more) that have a raw.lxc configuration key which is incompatible with the newer version of LXC that's in 3.0. You should unset this key and then run the upgrade again. "raw.lxc" is an unsupported configuration key in LXD which lets you directly configured underlying LXC without going through any of the backward compatibility and upgrade code, so such issues on upgrade are unfortunately pretty likely. ** 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/1784846 Title: package lxd 3.0.1-0ubuntu1~18.04.1 failed to install/upgrade: installed lxd package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxd/+bug/1784846/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
