Fails in install-hook #2

Closed migsk closed 5 years ago

Problem

After deployingjuju deploy cs:~tengu-team/jupyter-notebook-0 the charm fails in the install-hook.

Solution

I manually changed the pip import in /usr/local/lib/python3.5/dist-packages/charmhelpers/contrib/python/packages.py to from pip._internal import main.

This looks like an upstream issue with the charmhelpers library and the pip_install function?

I also had an error in the install hook when deploying cs:~tengu-team/jupyter-notebook-0. The error was:

I solved it by ssh'ing to the jupyter-notebook/0 unit and running the following command:

sudo python3 -m pip uninstall pip && sudo apt install python3-pip --reinstall

I notice the file /usr/bin/pip3 has been removed from the jupyter-notebook/0 unit:

Should be fixed by using cs:~tengu-team/jupyter-notebook-1.
