The unauthenticated git protocol on port 9418 is no longer supported

Question

I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs

Command: git
Arguments: ls-remote --tags --heads git://github.com/adobe-webplatform/eve.git
Directory: /home/runner/work/stackstream-fe/stackstream-fe
Output:
fatal: remote error: 
  The unauthenticated git protocol on port 9418 is no longer supported.

Upon investigation, it appears that below section in my yml file is causing the issue.

    - name: Installing modules
      run: yarn install

I have looked into this change log but can't seem to comprehend the issue.

package-lock.json

Answer 1

@toast-ui/react-chart dependency is causing issue for you here.

If you look closely inside your package-lock.json you can backtrack eve to @toast-ui/react-chart

eve --> raphael --> tui-chart --> @toast-ui/react-chart

You can follow this same technique to find any more issues inside your project.

Answer 2

First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".

January 11, 2022 Final brownout.

This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.

Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.

As noted by Jörg W Mittag:

There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.

Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".

Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.

The permanent shutdown is not until March 15th.

For GitHub Actions:

As in actions/checkout issue 14, you can add as a first step:

    - name: Fix up git URLs
      run: echo -e '[url "https://github.com/"]\n  insteadOf = "git://github.com/"' >> ~/.gitconfig

That will change any git://github.com/ into https://github.com/.

For local projects

For all your repositories, you can set:

git config --global url."https://github.com/".insteadOf git://github.com/

---

You can also use SSH, but GitHub Security reminds us that, as of March 15th, 2022, GitHub stopped accepting DSA keys. RSA keys uploaded after Nov 2, 2021 will work only with SHA-2 signatures.
The deprecated MACs, ciphers, and unencrypted Git protocol are permanently disabled.

So this (with the right key) would work:

git config --global url."[email protected]:".insteadOf git://github.com/

That will change any git://github.com/ (unencrypted Git protocol) into [email protected]: (SSH URL).

Answer 3

Try using the following command before install:

git config --global url."https://".insteadOf git://

P.S. or better ( thanks @bgraves )

git config --global url."https://github.com/".insteadOf git://github.com/

Answer 4

Try using https://github.com instead of git://github.com

Answer 5

Change git://github.com/<blah> to [email protected]:<blah> (note the / ? : at the end) in your repository's .git/config file.

In my repository's .git/config file I had this line

[remote "upstream"]
    url = git://github.com/curlconverter/curlconverter.git
    fetch = +refs/heads/*:refs/remotes/upstream/*

which I changed to

[remote "upstream"]
    url = [email protected]:curlconverter/curlconverter.git
    fetch = +refs/heads/*:refs/remotes/upstream/*

and stopped getting this error.

Answer 6

I hope this answer would provide more context omitted in the other answers.

Git can use four protocols to transfer data:

• Local (not relevant here)
• (Smart) HTTP - runs over standard HTTPS ports, and can use various HTTP authentication mechanisms (e.g. username/password) if authentication is required. This protocol allows you to provide both read and write access using the same URL; if authentication is required, the server will prompt the client.
• Secure Shell (SSH) - authenticated workflow where both reads and writes are authenticated. It does not support unauthenticated (i.e. anonymous) access. Users need to generate an SSH key pair (containing a private and public key) locally and upload their public key to the server.
• Git protocol - unencrypted and unauthenticated. There is a Git Daemon that runs on the Git server that listens on port 9418 and services requests.

Each of the protocols uses different URLs:

• Local:
  • Absolute path (e.g. /srv/git/project.git)
  • Absolute path prefixed with file:// protocol (e.g. file:///srv/git/project.git)
• HTTP: https://example.com/gitproject.git
• SSH
  • ssh://[user@]server/project.git
  • Shorter SCP-like syntax - [user@]server:project.git
• Git protocol - Starts with git://

GitHub has dropped support for all unencrypted protocols, which only includes the Git protocol (those that uses the git:// prefix). Thus, the The unauthenticated git protocol on port 9418 is no longer supported. error confirms this.

The way to mitigate this is by searching for the string git:// within your package.json and lockfiles (e.g. yarn.lock or package-lock.json) to identify the offending package(s), and upgrade them to a version that does not use dependencies that resolves to a URL with the git:// prefix. If the offending package is not in your package.json, you may find it helpful to run a command like yarn why to understand why the package is installed.

If that's not possible, and the repository is public, a temporary solution would be to manually replace git:// with https://. But this solution is not permanent and may get overwritten the next time the lockfile is written to.

Answer 7

When all of the other solutions don't help, try editing your global config and removing all instead of declarations.

git config --global --edit

Answer 8

Add the code into ~/.gitconfig:

[url "https://"]

    insteadOf = ssh://

[url "https://"]

    insteadOf = git://

Answer 9

If you are getting this issue while running something like pip install git+git://github.com/SomeCompany/somerepo.git@sometag, then only the second part of git+git needs to change, i.e. it becomes pip install git+https://github.com/SomeCompany/somerepo.git@sometag

Answer 10

Hello try the below options - this one worked for me

git config --global url."https://github".insteadOf git://github

Now git hubwont support unauthenticated git protocol https://github.blog/2021-09-01-improving-git-protocol-security-github/

I was getting the bellow error
