Conda install and update do not work also solving environment get errors

I ran into the same problem and I couldn't find a solution, but I did find a workaround. If you create an env and activate that env and then do the install, it seems to work just fine. If you don't need a lot of libraries I would try that.

Commands are:

  1. Create env
conda create --name myenv
  1. Activate the env
conda activate myenv

I started running in to this problem when one package suggested following modifications before installation

conda config --set channel_priority true

so I just reverted it and voila error's gone

conda config --set channel_priority false
