The Private Internet Access (PIA) client can also cause this problem. Somebody wrote a blog post about tracking this down: https://ryan.himmelwright.net/post/pia-client-podman-issues/

The smoking gun is file ownership:
$ ls -l /sys/fs/cgroup/net_cls
shows "piavpn" as the group owner.

As stated above, a temporary workaround is
$ sudo umount /sys/fs/cgroup/net_cls

Or for a permanent fix, uninstall the PIA client and reboot.

Now that there is a FOSS version of the PIA client, a bug report was filed (still open):

I'm posting here because search engines seem to point to this page, and seeing this may prevent others from blaming LXD incorrectly.
