Cura 5.1.0 on Linux Mint 20.2 Uma/20.3 Una (Ubuntu 20.04 Focal Fossa)

[jayrugman 0]

Has anyone been able to get Ultimaker-Cura-5.1.0-linux.AppImageCura (or any cura 5 appimages) to work on Linux Mint 20.2 (UPDATE: I upgraded to Mint 20.3 and still have the same issue with Cura 5)?  Ultimaker_Cura-4.13.1.AppImage works fine. I've scoured the web and haven't found anything recent - for Cura version 5. I'm raelly excited about the new slicer features and want to get it working soon.

 

Here is the output when I run it from the command line (I get the initial splash screen, then it hangs for a really long time until I cancel):

 ./Ultimaker-Cura-5.1.0-linux.AppImage                                   
PyInstaller/loader/pyimod03_importers.py:495: DeprecationWarning: the imp module is deprecated in favour of importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses
QApplication: invalid style override 'kvantum' passed, ignoring it.
    Available styles: Windows, Fusion
QQmlApplicationEngine failed to load component
QQmlComponent: Component is not ready
^C

 

The logs look like there are many missing dependencies. Correct me if I'm wrong, but aren't app images supposed to contain the dependencies? At any rate, I see a ModuleNotFoundError saying "No module named 'PyQt5'." Is this a Python module?

 

When I try to install this with pip3, it looks like I already have it:

pip3 install PyQt5       
Requirement already satisfied: PyQt5 in /usr/lib/python3/dist-packages (5.14.1)

 

I guess the appimage isn't using my local python modules or it's a module for something else? If so, what? 

 

I also see a number of plugin import errors. Are there plugins I should remove from within Cura 4 so I can successfully start version 5?

 

I have attached error and warning logs from /home/my-user/.local/share/cura/5.1/cura.log  and can post more upon request.

Thanks a Ton for any help!!

@alfcura - Thanks for the response. Sorry for not updating this sooner, but I found an answer on another forum (I want to say the cura git page). From what I found, I created a script tor starting Cura and linked it to the icon which is very similar to your suggestion, so thanks again.
