Inkcut does not start on Kubuntu 20.04 LTS #309

I had similar issues on RPI 4 8GB with latest Ubuntu 64 bit desktop and with latest Raspberry Pi 32 bit OS. I had this working on a headless Pi 3 B with Raspbian (created about a year ago) it still works. Something has changed. |
Yes! But it must not be only a matter of inkcut. I assume it has something to do with pathes and python versions. The missing file (sip) is there in different places and I think inkcut does not find the right one. But I am not python and QT expert enough to solve the issue myself. |
|
I tried manually installing python 3.9 buy i still couldn't get qtconsole installed without errors. |
|
If I try to import in python3 console the result is: So sip can be imported but not from PyQt5. Any idea? |
|
I think I figured this out. Fresh install of Ubuntu on RPI4. The install process that worked for me was: sudo apt update I also added the .local/bin to the path so the inkcut command would work: (note use your username instead of jrp) |

Update: Didn't work on Raspberry Pi OS. Didn't work on Ubuntu 20.10. Did work on Ubuntu 21.04. Unfortunately, 21.04 uses Wayland and that didn't work with the Raspberry Pi Element 14 7-inch touchscreen. |
|
Tried solution on Ubuntu 20.04. It doesn't work. |
|
Same problem on Debian 10. |
|
Hi, same problem on Ubuntu 20.04 and same workaround as explained by @veego. Thanks! |
|
Unfortunatly it does not work here: And the disadvantage of changing the pyqt5 lib to a lower version is, that some other modules will not work anymore. e.g. freecad module draft stops by not finding the right qt-version. |

Has this been fixed... trying to install on raspbian (latest) running on RPi 4 with 2GB. Have tried all the potential solutions here... but with no success pi@piBCNC:~/Downloads/inkcut-2.1.3 $ inkcut 2021-06-17 04:01:15,224 | CRITICAL | inkcut | Sorry, an error prevented Inkcut from startingThis is either a bug or a required library may be missing on your system. As always you can request help on the forums at https://inkcut.org. First try to restart the application. If the error persists you can try clearing the saved settings in /home/pi/.config/inkcut and restart the application again. If that still doesn't work please report a new issue at https://github.com/codelv/inkcut with the following error: plugin = manifest.factory()

I found a solution to the problem! You need to edit the file: ~/.local/lib/python3.7/site-packages/pyqtgraph/Qt.py and install package sip if needed I don't know English well I write through a translator |
Same issue here on Mint 20.2 XFCE Using the older version of Qt works, but not sure if it'll affect anything else yet. |
