Alternatively, Micromamba can be used. Micromamba is really fast:
https://waylonwalker.com/install-micromamba/


micromamba search qgis -y -c conda-forge
micromamba create -n aqgis qgis pcraster -y -c conda-forge

micromamba run -n aqgis qgis

micromamba activate aqgis
micromamba list
qgis

micromamba update
micromamba update qgis
qgis

micromamba deactivate

#Caution, this will delete the envirement aqqgis:
micromamba env remove --name aqgis


Greetings
Christian
