Conda: Channel is unavailable/missing or package itself is missing

Cause

After you have configured your .condarc for either Team Edition or Commercial Edition, in some cases you may be unable to install packages. You may receive an error message that the channel or package is unavailable or missing.

Solution

One potential fix for all of these is to run the following command:

conda clean -i

This will clear the “index cache” and force conda to sync metadata from the repo server.

403 error

Cause

A 403 errors is a generic Forbidden error issued by a web server in the event the client is forbidden from accessing a resource.

The 403 error you are receiving may look like the following:

Collecting package metadata (current_repodata.json): failed

UnavailableInvalidChannel: The channel is not accessible or is invalid.
  channel name: pkgs/main
  channel url: https://repo.anaconda.com/pkgs/main
  error code: 403

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.
There are several reasons a 403 error could be received:

There are a few possible reasons for receiving this error:

  • The user has misconfigured their channels in their configuration (for example, the secure location where the token is stored was accidentally deleted (most common)
  • A firewall or other security device or system is preventing user access (second most common)
  • We are blocking their access because of a potential terms of service violation (third most common)

Solution

  1. First, run the following to undo your configuration of Commercial Edition:

    conda config --remove-key default_channels
    
  2. Next, install or upgrade the conda-token tool:

    conda install --freeze-installed conda-token
    
  3. Lastly, re-apply the token and configuration settings:

    # Replace <TOKEN> with your token
    conda token set <TOKEN>
    

If this doesn’t resolve the issue, we recommend consulting our Terms of Service error page.

HTTP 000 CONNECTION FAILED

If you receive this error message, first run the following command:

conda config --set ssl_verify false

Then, run the following to install conda-token:

conda install conda-token -n base

Lastly, run the following to ensure the token verification step ignores SSL errors:

# Replace <TOKEN> with your token
conda token set --no-ssl-verify <TOKEN>

You may see the following warning, though this is to be expected:
