What happened?

I tried to install the motor=3.5.1 package, but got the following result:

UnavailableInvalidChannel: HTTP 403 FORBIDDEN for channel intel <https://conda.anaconda.org/intel>

The channel is not accessible or is invalid.

I know that the intel channel on conda.anaconda.org is no longer valid, and I have removed it from my .condarc file. However, when I try to install this package using the libmamba solver, it somehow adds the intel channel to the channels that I currently have configured. When I am not using the libmamba solver, it does not do this.

From 23.9.0 on, conda-libmamba-solver won't try to use channels that are unavailable. I'd recommend to upgrade. To prevent the error, you can set this environment variable: CONDA_LIBMAMBA_SOLVER_NO_CHANNELS_FROM_INSTALLED=1.
