That did the trick!!!
Thank you very much!
I had restarted the container but had not restarted lxd.
One point that would help, at least IMO, would be if all the lxc commands were modified to lxd commands. It would be then easier to confirm that one is working in lxd.
Something that (IIRC) you are doing but isn’t too common is to date blog entries or other informational blurbs. I have learnt to distrust such without dates as their methodology is far too often severely deprecated most often because the techniques are outdated.
Thank you for your very generous help!!!
