Collecting package metadata (current_repodata.json): failed

UnavailableInvalidChannel: The channel is not accessible or is invalid.

You will need to adjust your conda configuration to proceed.
Use conda config --show channels to view your configuration’s current state,
and use conda config --show-sources to view config file locations.
