I have added the channel “stcorp” using Anaconda Prompt. But when I am trying to download packages using this channel it says " UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel stcorp [https://conda.anaconda.org/stcorp](https://conda.anaconda.org/stcorp)
The channel is not accessible or is invalid.
You will need to adjust your conda configuration to proceed."
I am stuck with this for quite some time. Please help me in this regard.

You shouldn’t use the stcorp channel anymore. You should only use the conda-forge channel.
Where did you find that the stcorp channel should be used? If there is some documentation that we forgot to update, I would like to know.

I found it here. ([GitHub - bilelomrani1/s5p-tools: Python scripts to download and preprocess air pollution concentration level data aquired from the Sentinel-5P mission](https://github.com/bilelomrani1/s5p-tools#installation))

Unfortunately the information in that github repository is outdated. You might want to raise it as an issue there, although the repository itself seems to have been archived, so it is not likely to get fixed there.
