3 weeks ago I can reproduce the error with the same configuration. I already had this problem in the past due to the use of Numba lib in QGIS but this was for Windows and I have never received any answer ().
However, installing QGIS and UMEP into Ubuntu 22.04 should not be an issue if you are allow and willing to use conda or mamba environments (https://github.com/UMEP-dev/UMEP/discussions/585#discussioncomment-8181433).
If so I recommend to install mamba (https://mamba.readthedocs.io/en/latest/user_guide/mamba.html) and to simply do the following in a terminal:
mamba install -n myQgisUmepEnv gdal qgis jaydebeapi "numpy<2.0.0" numba netCDF4 pandas scipy matplotlib xarray unidecode mamba activate myQgisUmepEnv qgis
Describe the bug The install of UMEP crashes when I try to install it on Ubuntu 22.04 and QGIS 3.22.4. I'll see if I can figure out what is going on. I assume it is the older version of QGIS. It is the most recent version available for 22.04.
I was able to successfully install it on Fedora 40 and QGIS 3.34.
Couldn't load plugin 'processing_umep' due to an error when calling its classFactory() method
