I work with QGIS 3.32.2-Lima on Ubuntu.

I would like to install and use this useful plugin :

https://plugins.qgis.org/plugins/spectral_libraries/

But it seems to be deprecated?

So when I try to install it with QGIS, I get an error message below: If this plugin does not work anymore, what would be any alternative with QGIS?

A quick search of PyPI shows that the mock library is available for installation. Try installing mock with pip, try again, and report back. QGIS on Linux uses the regular Python interpreter so the library installation is no different than any Python library installation.

Your question asks for alternatives for QGIS. The QGIS/Orfeo toolbox processing toolset should have all the tools you need. You do not specify what tools you need exactly but here is a link to the Orfeo Cookbook.

  • Thanks for your message. But OTB does not really match to my request for the error message resolution (miss python mock module). As far as i understood, my error message deals with a missing qgis python mock module. /usr/lib/python3/dist-packages/qgis Do you know how to install this module specifically for the python qgis ?

  • 1. Open OSGeo4WShell. It is installed with QGIS. 2. Install the missing Moduls with pip. 3. Restart QGIS Commented Nov 3, 2023 at 8:52
