Hello everyone ! For one of my course I am required to create a new environment. The navigator used to be working just fine but this time it is impossible for me to get it work. Every time that I am trying to create an environment I get this error message:  
UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel gurob [http://conda.anaconda.org/gurob](http://conda.anaconda.org/gurob)  
  
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.\<br

From what I understand, my current configuration needs to be changed, how to I remove something from it ?
