Since a couple of days ago it seems like powerline have stopped working? When I opened konsole I got "bash: /usr/lib/python3.6/site-packages/powerline/bindings/bash/powerline.sh: Filen eller katalogen finns inte" (file or directory doesn't exist).

Has something changed? I have a couple of poweline related executable files ;

powerline
powerline-config
powerline-daemon
powerline-lint
powerline-render

In global bashrc file I have these lines (that worked before something changed).

powerline-daemon -q
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
. /usr/lib/python3.6/site-packages/powerline/bindings/bash/powerline.sh

What owns /usr/lib/python3.6/site-packages/powerline/bindings/bash/powerline.sh, you should not have any in python3.6 anymore, that is why the 100+ rebuilds for python 3.7.2.
If that file doesn't exists, then make sure you edit any file you have in your home dir to point to python3.7 instead of python3.6.

Ah right! Changing the line to ../python3.7/.. made the trick 🙂 Didn't realize it had changed.

Thanks demn!
