PPA problem updating to Release of 0.18

[iogui]

@kkremtzki, you are not counting with qt5 from universe repository, right?

https://packages.ubuntu.com/xenial/qt5-default

Ok... So I think I will have to reinstall all my system to be able to use FreeCAD with python 3.

[kkremitzki]

Yeah, the problem is that it's version 5.5.1 when I think 5.9+ is required.

How much of a problem do you think there might be with Python add-ons being py2 only or py3 only? I read here others seemed to be saying that you could write code that would work in both but I have no idea myself. If it is likely that there will be compatibility problems then perhaps another answer could be to modify the add-ons installer so that it only offers add-ons to suit the python version available, rather than making FreeCAD Py3 available everywhere where it is very difficult/impossible. Or is this pretty much a non-issue?

[kkremitzki]

Hmm, given that Python 2 is EOL on January 1st it's probably not worth it to spend too much time on it for how much we would gain.

[reox]

+1 for python3 only.
Porting code from py2 to py3 is challenging but has to be done only once. Supporting both versions results in many hours of frustration

Behavior of FreeCAD at launch after updating from stable PPA on clear profile:

[kkremitzki]

It's strange that there are no error messages being displayed... when you say "with a clear profile" do you mean you've tried temporarily moving your ~/.FreeCAD directory? Can you try running dpkg -l | grep freecad?

[doubters]

Deleted ~/.FreeCAD and ~/.config/FreeCAD for clear experiment.

Pasting the terminal output in plain text here would be more useful than this animated GIF, which goes too fast for us to see.

[kkremitzki]

Yes, the relevant error messages flash by and there's no rewind or playback controls.
