UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel

### Your question:

Hello Everyone,
I am having an issue with running channels on conda. I am trying to run this command `conda create --name --file ` but I keep getting this error: UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel. When I initially ran 'conda create...' I got this error:

```
Collecting package metadata (current_repodata.json): done
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

- barrnap==0.9=hdfd78af_4
- hmmer==3.4=hdbdd923_1
- iqtree==2.3.0=h21ec9f0_0
- bedtools==2.31.1=hf5e1c6e_1
- mafft==7.525=h031d066_1
- ete3==3.1.3=pyh1d129d4_0

Current channels:

- https://conda.anaconda.org/conda-forge/linux-64
- https://conda.anaconda.org/conda-forge/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

https://anaconda.org

and use the search bar at the top of the page.
```

Since I didn't have the appropriate channels I did `conda config --add channels ` for all the channels that I needed. Then I get this error:

```
Collecting package metadata (current_repodata.json): done
Solving environment: done

UnavailableInvalidChannel: HTTP 404 NOT FOUND for channel mafft

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.
```

I have tried clearing the cache by doing `conda clean -i` then I tried rerunning; got the same error. Removed all the channels with `conda config --remove-key channels`. Re-added all of the channels but I am still getting the same error. Any suggestions on what I could do to fix this would be much appreciated. Thank you for your time!
