[ldesousa]

Running QGis 3.34.10-Prizren on Ubuntu 24.04, installed with Nix to the user profile. The plug-in fails to install as it cannot find a Python library. The full log is below.

Couldn't load plugin 'sparqlunicorn' due to an error when calling its classFactory() method

This looks an issue with dependencies in Nix. I will leave this issue open an report back once I get more details.
