Comment 12 for bug 1770090

I did a minimal installation of 18.04 (desktop). Logged in, opened a terminal, typed byobu, not installed, installed it with apt.

byobu itself, as well as byobu-config, worked out of the box.

I also have newt installed, in terms of python3-newt and libnewt0.52, and tmux 2.6-3.

I don't know how you get from running byobu to getting an error about "snack". The only snack I see in ubuntu 18.04 is python{,3}-tksnack, which is something about audio/sound.

Do you have some byobu customization to call out to this "snack" python module you have? Did you install the py3 version of that module from pip?
