Bundled plugins TrimeshReader and AMDReader fail

[Tomas Hlavacek]

After upgrading to Jammy I encountered the errors caused by the bundled plugins TrimeshReader and AMFReader. The first is probably caused by the missing trimesh PIP package.

Same here. After the update to Jammy, Cura cannot load AMFReader and TrimeshReader plugins.

Here are some of the related Cura logs if it may help:

Status changed to 'Confirmed' because the bug affects multiple users.

[Kyr4l (kyr4l)]

same issue, is it gonna be resolved ? the package is also outdated, cura 5.1.1 is available atm

[Gavin Robertson (ubuntu-tatooine)]

Caused by unavailable python3-trimesh package. Install trimesh via pip and plugins will load correctly.

pip install trimesh worked for me too. Thanks
