Any idea how to fix this?

# lxc list
Error: Get "http://unix.socket/1.0": EOF

In the log, it complains “Error: Failed to load network “lxdbr0” in project “default”: sql: Scan error on column index 2, name “description”: converting NULL to string is unsupported”:

This has been fixed in the latest snap which should be being deployed soon.

Waiting for two more architectures to be done building, it looks like another 24h.

Sorry for the delay on the snap update, Launchpad which is used to build it has been very very severely backlogged this week following the release of Ubuntu 21.10.
