I’ll have to go back to the machine to test that. Before I do that, I have to post something I found while searching online just now.
I found an old post with the same type of configuration as mine. The same error occurs on an Ubuntu host by the way. There is an explanation of where the renaming issue is occurring and it’s actually something done by lxc.
A solution was provided on the host server configuration which was not confirmed to work by the original author, but it was confirmed by someone else afterwards
