FWIW, I was able to reproduce this problem even inside a VM, which means that this is not related specifically to LXD containers.
Another interesting point here is the fact that a lot of important systemd services are unable to restart after the libc upgrade. We end up with a system without internet connectivity, for example. I'm adding a glibc task to this bug and a block-proposed tag, as well as retitling it. ** Also affects: glibc (Ubuntu) Importance: Undecided Status: New ** Changed in: glibc (Ubuntu) Importance: Undecided => High ** Tags added: block-proposed ** Summary changed: - docker 20.10.7-0ubuntu2 fails to start when installed inside Impish LXD container + glibc 2.34 upgrade will break some essential services -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1942276 Title: glibc 2.34 upgrade will break some essential services To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1942276/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
