joinmarket-qt missing package and error

[8aph0ivi37]

ubuntu 22.04, joinmarket-clientserver-0.9.6 installed by install.sh with qt support
joinmarket-qt.py won't start, with error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted (core dumped)

retrying with export QT_DEBUG_PLUGINS=1:

Cannot load library /home/master/joinmarket/jmvenv/lib/python3.10/site-packages/PySide2/Qt/plugins/platforms/libqxcb.so: (libxcb-xinerama.so.0: cannot open shared object file: No such file or directory)

searching for missing package:

ldd /home/master/joinmarket/jmvenv/lib/python3.10/site-packages/PySide2/Qt/plugins/platforms/libqxcb.so | grep "not found"
libxcb-xinerama.so.0 => not found
libxcb-xinerama.so.0 => not found

installed libxcb-xinerama0

after that joinmarket-qt.py displays window and allows to select wallet, but then quits with an error:

Traceback (most recent call last):

The first part was a known issue (see #687 #737 and potentially related #1046 #1031 ), but the second one is strange as it looks like a pretty fundamental error! Although I haven't run Python 3.10 myself, I was under the impression that it worked. Just to sanity check is it possible you could try with 3.7/8/9 to check if it works on those?

I suppose Ubuntu2204 might be another delta, that's another setup I haven't tried.

installed python3.9 via deadsnakes ppa
then clean rebuild
./install.sh --python=python3.9
error solved!

Thanks for letting us know.

Any plans on adding support for Python 3.10?
