InvalidSpec: The package "conda-forge/noarch::adwaita-icon-theme==41.0=ha770c72_1" is not available for the specified platform

I'm following the installation steps as written in #a303cb395d4139710bf663f5a9b5e1bd59e3feb0.

When I run

conda env create -f environment.yml
conda activate gr310

# ...

conda install -c tapparelj -c conda-forge gnuradio-lora_sdr

... i get the following error message:

$ conda install -c tapparelj -c conda-forge gnuradio-lora_sdr
Channels:

Same InvalidSpec error message appears when executing conda install -c conda-forge gnuradio .

Maybe I'm mixing up steps that should be run outside of the gr310 environment? I don't know if it makes for the cmake/make commands any difference whether they are executed in a / the gr310 environment.
