This page details some common issues and their respective workarounds. For Anaconda installation or technical support options, visit our support offerings page.

​
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:
  • The user has misconfigured their channels in their configuration (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

If you have ruled out the first two reasons to your 403 error, then we recommend consulting our Terms of Service error page to resolve the matter.

If you experience any trouble regarding SSL errors, confirm that you are adhering to the guidance in this section.

​
Moving CA certs to the docker-host

We recommend mounting the cacert.pem file to the docker-host and concatenating the required root CAs to that file on the docker-host, rather than copying the file to the containers.

  1. First, place a cacert.pem file in ${BASE_INSTALL_DIR}/config/cacert.pem. You can obtain this file from any conda environment with certifi package installed ($<CONDA_PREFIX>/ssl/cacert.pem) or from one of the TE docker containers:

    # Replace {BASE_INSTALL_DIR} with your base install directory.
docker cp $(docker ps | awk '/repo_api/ {print $1}'):/conda/ssl/cacert.pem  ${BASE_INSTALL_DIR}/config/cacert.pem

  2. Concatenate the necessary root certs in pem format:

    # Replace <YOUR_CERT> with your cert and {BASE_INSTALL_DIR} with your base install directory.
cat <YOUR_CERT> >> ${BASE_INSTALL_DIR}/config/cacert.pem

  3. You now have two options for updating the TE application to use the docker-host cacert.pem:

    • Edit the docker-compose.yml file and add volume mounts to nginx_proxy, repo_api, repo_worker and repo_dipacher, or

    • Use a separate .yml file (shown below) and let docker-compose merge it with the stock one when starting up:

      cat << EOF > custom-cas.yml
services:
    nginx_proxy:
        volumes:
        - \${BASE_INSTALL_DIR}/config/cacert.pem:/conda/ssl/cacert.pem
    repo_api:
        volumes:
        - \${BASE_INSTALL_DIR}/config/cacert.pem:/conda/ssl/cacert.pem
    repo_worker:
        volumes:
        - \${BASE_INSTALL_DIR}/config/cacert.pem:/conda/ssl/cacert.pem
    repo_dispatcher:
        volumes:
        - \${BASE_INSTALL_DIR}/config/cacert.pem:/conda/ssl/cacert.pem
EOF
docker-compose -f docker-compose.yml -f custom-cas.yml up -d

​
Storing user credentials

If the proxy connection requires credentials, we recommend storing the credentials in the .env file (located in the same folder as the docker-compose.yml file) and referencing it in docker_compose.yml so that docker-compose.yml is readable for a broader set of users.

When TE is installed, an .env file is created alongside the docker-compose.yml file by default. You can edit this file and add variables to be referenced in the docker-compose.yml file as follows:

# example .env
BASE_INSTALL_DIR=/opt/anaconda/repo
DOCKER_REGISTRY=
DOMAIN=example.com
NGINX_PROXY_PORT=443
POSTGRES_HOST=postgres
POSTGRES_URI=postgresql://postgres:postgres@postgres/postgres
REDIS_ADDR=redis://redis:6379/0
VERSION=6.1.4
PROTOCOL=https
REPO_TOKEN_CLIENT_SECRET=something
REPO_KEYCLOAK_SYNC_CLIENT_SECRET=somethingsomething
DOCKER_UID=0
DOCKER_GID=0

# Added for example..
PROXY_USER=eden
PROXY_PW=eden-password

Then, merge the following with existing compose content in the docker-compose.yml file. Notice the environment variable from .env being referenced in the environment variables:

repo_worker:
  environment:
    - HTTP_PROXY=http://<PROXY_USER>:<PROXY_PW>@proxypy:8899
    - HTTPS_PROXY=http://<PROXY_USER>:<PROXY_PW>@proxypy:8899
repo_api:
  environment:
    - HTTP_PROXY=http://<PROXY_USER>:<PROXY_PW>@proxypy:8899
    - HTTPS_PROXY=http://<PROXY_USER>:<PROXY_PW>@proxypy:8899

​
Local mirrors

Another option is mirroring locally. You can do this by getting packages into an admin-managed channelsay, ananconda/mainand then mirroring filtered packages from that channel to other channels. This will make TE the source for the mirror. As such, TE needs to be able to validate its own certificate, which in most cases won’t work (in very much the same way PROXY with terminating SSL will not work).

For this to work, then, you will most likely need to update the cacert.pem file of all TE containers. For this reason, we recommend hosting the cacert.pem file on the docker-host instead of the containers.

​
SSL verification error

Cause

You may receive an SSL verification error if you have SSL enabled with a self-signed certificate.

Solution

Run the following command to disable SSL certificate check:

conda repo config --set ssl_verify False

Run the following to verify the above command worked:

conda repo config --show

​
Using Redis

Cause

By default, Redis does not require a password. Not enabling a password requirement leaves your instance of Team Edition vulnerable.

Solution

Follow these steps to password protect your instance:

  1. In the installation directory, update config/nginx/conf.d/repo.conf to include the add_header directive somewhere in the server block:

    server {
    ...
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    ...
}

  2. Create a directory called redis in the configs directory:

    mkdir -p config/redis

  3. Create a file called redis.conf inside config/redis with the following contents:

    requirepass "mypassword"

  4. Update the docker-compose.yml file of TE installation to mount this custom redis config:

    redis:
    image: ${DOCKER_REGISTRY}redis-ubi:${VERSION}
    restart: always
    volumes:
      - ${BASE_INSTALL_DIR}/config/redis/redis.conf:/usr/local/etc/redis/redis.conf

  5. Update REDIS_ADDR variable in .env file to include password:

    ...
REDIS_ADDR=redis://:mypassword@redis:6379/0
...

  6. Restart docker-compose services so changes are picked up. You can do this using:

    docker-compose up -d
