Pushing to GitHub Container Registry: unauthorized: unauthenticated: User cannot be authenticated with the token provided – Github

The Solutions:

Solution 1: Creating a Personal Access Token (PAT)

Steps:

1. Visit GitHub’s token creation page at https://github.com/settings/tokens.
2. Click on "Generate new token."
3. Enter a token description and select "read/write packages" permissions.
4. Click on "Generate token."
5. Copy the generated PAT to your clipboard.

Solution 2: Using the PAT to Authenticate Docker

Steps:

1. In your terminal, run the following command:

docker login ghcr.io -u username -p ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Replace "username" with your GitHub username and "ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" with the PAT you copied in the previous step.

Solution 3: Pushing the Image to GHCR

Now that Docker is authenticated with your PAT, you can push your image to GHCR using the following command:

docker push ghcr.io/username/imagename:latest
