Description picotmathieu 2017-06-06 10:28:11 UTC

Kde Neon 5.8.7 LTS (system up to date)

All my python qt5 or qt programs are broken.
Somes crash at start with segmentation fault.
Somes crash at start with this kind of error:
from PyQt5.QtWidgets import QApplication, [...]
RuntimeError: the sip module implements API v11.0 to v11.3 but the  module requires API v12.1

Comment 1 Jonathan Riddell 2017-06-06 10:53:48 UTC

what applications are you using to test it?

apt-cache policy python-qt4
apt-cache policy python-sip

Comment 2 Jonathan Riddell 2017-06-06 11:36:42 UTC

It works for me to run a pyqt app on latest Neon User LTS in virtualbox

Comment 3 Jonathan Riddell 2017-06-06 11:37:52 UTC

tested with both python2 and 3

Comment 4 picotmathieu 2017-06-06 18:35:35 UTC

Tested with all applications that I know they use python3 and qt (carla, cadence, qarte), note I have the KXStudio repositories installed.

Simple test I tried:

houston@houston-MS-74562:~$ python3
Python 3.5.2 (default, Nov 17 2016, 17:05:23) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from PyQt5.QtWidgets import QApplication
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: the sip module implements API v11.0 to v11.3 but the  module requires API v12.1
>>> from PyQt4.QtGui import QApplication
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
RuntimeError: the sip module implements API v11.0 to v11.3 but the  module requires API v12.1

Using python (2) and import QApplication seems to work.

for the terminal results:

Comment 6 picotmathieu 2017-06-07 09:38:53 UTC

That's allright. I finally find that is was user specific. I had an old configuration, I didn't remember. I remove python dirs in ~/.local/lib/ and it works perfectly.

Sorry for the inconvenience.
