TypeError: Pen(): arguments did not match any overloaded call

Hello, I have recently upgraded my Ubuntu from 20 to 22, and now I can't get Pronterface to work at all. It says:

WARNING:root:Could not setup DBus for sleep inhibition: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.ScreenSaver was not provided by any .service files
Traceback (most recent call last):

  File "/usr/lib/python3/dist-packages/printrun/gviz.py", line 197, in __init__
    self.mainpen = wx.Pen(wx.Colour(0, 0, 0), penwidth)
TypeError: Pen(): arguments did not match any overloaded call:
  overload 1: too many arguments
  overload 2: argument 2 has unexpected type 'float'
  overload 3: argument 1 has unexpected type 'Colour'

I also downgraded my Python version to 3.6, 3.7 or 3.9, and it still doesn't work. The app is stuck and I have to press Ctrl+C to exit. I also have reinstalled Pronterface. Again, no success

Hi @GkqqNkKC, thanks for reporting this. I am unable to reproduce it though. What's the output of the following commands on your machine?

$ python
>>> import wx
>>> wx.__version__

Mine looks like this:

$ python
Python 3.10.5 (main, Jun  8 2022, 09:26:22) [GCC 11.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import wx
>>> wx.__version__
'4.0.7'

This should have been fixed by #1224

[rockstorm101]

Ah, of course, that's it. Thanks a lot @hroncok. I'm afraid the Printrun version on Ubuntu 22.04 is not yet patched for this error. Patch is already in place in testing so it'll make its way through for 22.10.

Using Python 3.9 as a work around should work though. Remember to change the shebang line on /usr/bin/pronterface like:

- #!/usr/bin/python3
+ #!/usr/bin/python3.9

Duplicate of #1225. Closing.

almost 1 year passed an the issue is still present on Ubuntu 22.04 which is an LTS version !!!!

I suggest you contact the Ubuntu folks, I am afraid the exclamation marks are wasted here.

I have the same problem on Ubuntu

@zhennik26,
as already stated, please contact the Ubuntu team. We can't do anything on this as we do not build the applications for the different Linux distros.
Alternatively you can run it from source following the instructions: https://github.com/kliment/Printrun#running-from-source.
