Having a similiar issue. When trying to add the key it hangs and never returns.

Based on the error it appears the .gnupg folder may be missing from /root.

Try running this command and see if the folder is there (first line is command and second line is output)…

sudo ls -al /root | grep gnu
drwx------  3 root root   4096 Aug 12  2019 .gnupg

If it is missing try seeing if the package is installed on your system…

sudo apt list gnupg
Listing... Done
gnupg/focal-updates,focal-updates,focal-security,focal-security,now 2.2.19-3ubuntu2.2 all [installed]

The other thing you could do is run everything in Docker. I switched to Docker several years ago and have been running trouble-free for a long time. It does simplify many things. Here are what containers I am running on my media server which is also running Ubuntu like you…
