Pushing from Eclipse to my GitHub repository via HTTPS stopped working: "git-receive-pack not permitted" error


I recently did a push to my GitHub repository for a few weeks ago. I got a main from GitHub that GitHub is soon quitting regular authorization and going to replace it with another authorization method.

So today I push a new update to my GitHub repository and got the message:

git-receive-pack not permitted

That's leads to two questions:

  1. Has EGit stopped working now?
  2. I have Eclipse 2021-03, how can I fix this issue so I can do a push?

Solution

  • Since August 13, 2021, GitHub does not support authentication via HTTPS with your GitHub account password for security reasons anymore. Instead, in Eclipse, when pushing to a GitHub repository or when fetching from a private repository, you will get a git-upload-pack not permitted on 'https://github.com...' error.

    As solution, use either

    Personal access token (GitHub specific)

    enter image description here

    1. Go to your GitHub account to Settings > Developer settings > Personal access tokens website:
      1. Click the Generate new token button in the upper right
        • Enter a Note, e.g. GitHub repo token
        • Choose Expiration, e.g. No expiration
        • Tick the checkbox repo
      2. Click the Generate token button at the bottom
      3. Copy the generated token to the clipboard
    2. In Eclipse, in the Git Repositories view:
      1. Right-click the Remotes sub-node for GitHub (origin or the name you have chosen when you have cloned the repository) and choose Configure Push...
      2. Click the Change... button to change the URI in the upper right
      3. Replace the password with with the copied generated GitHub token
      4. Click Finish and Save to apply the changes

    SSH

    1. Create an SSH key (skip this step when you already have one):
      1. In Eclipse, in the preferences General > Network Connections > SSH2 tab Key Management hit the Generate RSA Key... button
      2. Hit Save Private Key... and choose a location, preferably the subfolder .ssh of your user home directory
    2. Upload public key to your GitHub account:
      1. For a new created key, copy the string shown in the Key Management tab to the clipboard; for an existing key add it in the preferences General > Network Connections > SSH2 tab General and copy the content of the public key file <name>.pub
      2. Go to your GitHub account settings to the SSH and GPG keys section and hit the New SSH key button
      3. Paste the copied public key into the Key field
    3. Change HTTPS to SSH URLs of already cloned repositories:
      1. In Eclipse, in the Git Repositories view right-click the repository and choose Properties and click the Open button
      2. In the text editor of the config file change the remote URL as follows:

        HTTPS (old; does not work for push anymore):
        url = https://github.com/<username>/<repo>.git

        SSH (new):
        url = git@github.com:<username>/<repo>.git
