I want to have these requirements running on Ubuntu 22.04 LTS:
# Bug on Ub.22.04 but avoids AttributeError: 'Timer' object has no attribute 'start' on other OS
pyqt5==5.15.7
# These together work:
mayavi==4.7.4
PyVirtualDisplay==3.0
pytest==7.1.2
So I can run this test:
import pytest
from pyvirtualdisplay import Display
import os
display = Display(visible=0, size=(1280, 1024))
display.start()
from mayavi import mlab
def foo(tmp_path):
assert 0 == 0;
Adding the PyQt5 to the list of dependencies seems to break the behavior of the program on Ubuntu 22.04 LTS (although it works on Ubuntu 20.04 LTS and MacOS for multiple version of Python 3.
The output error is the following:
Run python3 -m pip install pytest
python3 -m pip install pytest
cd tests
python3 -m pytest
shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
Defaulting to user installation because normal site-packages is not writeable

/home/runner/work/_temp/0585cdff-a041-431e-b28d-a33e621d22b2.sh: line 3: 6351 Aborted (core dumped) python3 -m pytest
I created a small repo to reproduce the issue. I created a bunch of branches where I cut some python dependencies off until I could isolate pyqt5 as the one breaking the working state: the changes are documented in the README. I know using external repos is not ideal, but since in that case it is a Github Action problem (it works on my local Ubuntu 22.04), maybe it makes sense?
So the problem is that the system dependencies of PyQt5 (the python wrapper for Qt) were not installed on Ubuntu 22.05.
I initially tried to install the required system dependency qt5-default (that is, what worked for Ubuntu 20.04), but as stated here and here, the qt5-default package was removed in Ubuntu 21.04 and at the time I assumed (misinformed decision) that it was because the package was now shipped with the distribution. Well, it's not ^^
The way around is to install the qt5-default dependencies, with:
sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools
That was enough to make the project run on Ubuntu 22.04 LTS, and it was obviously my mistake, but I wonder what in the error message could have put me on the right track (missing system dependency) a bit sooner.
