I was away for a week and dutifully did all my software updates upon
returning. After updating Dom0 the qube-manager that was running started
having problems, so I restarted it, but it then refused to run.
RuntimeError: the PyQt4.QtCore and PyQt5.QtCore modules both wrap the
QtObject class
The problem appears to be qube-manager/python3 is first picking up
references to PyQt5 when first launching, and later it is picking up
some PyQt4 references via
/usr/lib64/python3.5/site-packages/qubesadmin/__pycache__/*.pyc files,
which then load files from
/usr/lib64/python3.5/site-packages/PyQt4/__pycache__/* , and thus
PyQt4/QtGui.so gets loaded.
It looks like the qubes-manager-4.0.22-1.noarch is the latest, though I
can't help but think this is a case of cache poisoning or some Qt4/Qt5
environment issue. If so, can the __pycache__/*.pyc files be removed and
regenerated, or is there another way to avoid the mixing of PyQt versions?
thanks,
Steve
