Byobu not working on new installation of macOS

I am trying to migrate from Linux to macOS, but apparently byobu is not working out-of-the-box on my machine. The Fn keys partially work. I can see the error message "no previous windows" and "no next windows" when I press F3 and F4, but pressing F2 does not succeed into creating a new window in byobu terminal.

I cannot find the right shortcut to split the terminal. I am trying to reconfigure byobu to specify my escape-sequence. Unfortunately, I cannot get rid of the following error:

(base) ➜  ~ byobu-config 
ERROR: Could not import the python snack module

To me, it seems that the snack module is old, as the errors I see are related to print functions not having parenthesis (which were made mandatory in python3).

(base) ➜  ~ which python3
/opt/homebrew/bin/python3


(base) ➜  ~ python3 -m pip install snack

Do you have any idea how to make byobu work on macOS?

Thank you!

Solution 1:

The problem is snack. Its home page is https://pypi.org/project/snack/

It gives requirements as python 2.7 and does not mention python 3.

So it needs to be ported to python 3.
