gnutls_handshake() failed: Handshake failed GIT

Question

Everything was working fine but suddenly I am getting the error:

fatal: unable to access 'https://[email protected]/name/repo_name.git/': gnutls_handshake() failed: Handshake failed

I am getting this on my computer as well as an EC2 instance. When I tried on another computer then it is working fine there.

I have tried many solutions from Stackoverflow and from other forums. but nothing worked!

On the computer, os is Linux mint 17 and on EC2 instance, Ubuntu 14.04.6 LTS.

What can be the issue and what should I do to fix this issue?

Answer 1

Ran into the same issue on a server with Ubuntu 14.04, and found that on Aug 24, 2020 bitbucket.org changed to no longer allow old ciphers, see https://bitbucket.org/blog/update-to-supported-cipher-suites-in-bitbucket-cloud

This affects https:// connections to bitbucket, but does not affect ssh connections, so the quickest solution for me was to add an ssh key to bitbucket, and then change the remote from https to ssh.

The steps to change the remote I found from here, and they are essentially:

# Find the current remote
git remote -v

origin  https://[email protected]/reponame.git (fetch)
origin  https://[email protected]/reponame.git (push)

# Change the remote to ssh
git remote set-url origin [email protected]:reponame.git

# Check the remote again to make sure it changed
git remote -v

Answer 2

The quickest solution is to use SSH instead of HTTPS. I tried other ways to fix the issue but it was not working.

The following are steps to replace HTTPS from SSH:

1. Generate ssh key using ssh-keygen on the server.

2. Copy the public key from the generated id_rsa.pub file from step 1 and add it at following links depending on the repository host -

   Bitbucket - https://bitbucket.org/account/settings/ssh-keys/

   Github - https://github.com/settings/ssh/new

   Gitlab - https://gitlab.com/profile/keys

3. Now run the following command to test authentication from the server command line terminal

   Bitbucket

   ssh -T [email protected]

   Github

   ssh -T [email protected]

   Gitlab

   ssh -T [email protected]

4. Go to the repo directory and open .git/config file using emac or vi or nano

5. Replace remote "origin" URL (which starts with https) with the following -

   For Bitbucket - [email protected]:<username>/<repo>.git

   For Github - [email protected]:<username>/<repo>.git

   For Gitlab - [email protected]:<username>/<repo>.git
