I have the same problem. Same OS and version. Any news on this?

Same problem. Same OS.
I tried using several python versions 3.7-3.10, to no avail.

I browse through the packages mentioned in the error. It seems lookatme is GNU/Linux strictly since urwid uses a module called fcntl.

Hmm, you're right about the fcntl problem... let's keep this issue open and see what can be done.
