Comment 7 for bug 1803558

Is true, few minutes ago I managed to make it work under py36/py37 so I no longer need any other change.

I can see your concern about external to LP, while it can sort some problem it could create many more. Maybe switching from bzr to git in linger run would be a nice step, as i see it as supported https://help.launchpad.net/Code/Git#Converting_from_Bazaar_to_Git

And thanks for helping with that!
