I keep getting this weird error when trying to push my code to my remote repository. Has anyone run into this before and figured out how to fix it?
I’m working from my terminal and I’m in my project’s main directory. The repository definitely exists on the remote server but something is blocking me from pushing.
Here’s what happens when I try to push:
$ git push origin main
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I’m not sure if this is an authentication issue or something else. Any ideas on what might be going wrong here? I’ve been stuck on this for a while and could really use some help getting my code uploaded.
This happens when Git can’t authenticate with the remote server over SSH. Even with SSH keys set up, they might not be loaded into your SSH agent - that caught me off guard when I hit this issue. Run ssh-add ~/.ssh/id_rsa to add your private key to the agent. Double check your remote URL format with git remote -v. If it’s showing HTTPS, either switch to SSH format or use HTTPS with a personal access token instead.
It seems like your SSH key isn’t set up correctly or the server isn’t recognizing it. If you haven’t generated a key yet, you can do so by running ssh-keygen -t rsa -b 4096 -C "[email protected]". Once created, you can retrieve your public key using cat ~/.ssh/id_rsa.pub and add it to the SSH keys section of your Git host. To verify if everything is working correctly, you can test the connection with ssh -T [email protected]. I encountered a similar issue recently where I forgot to upload the public key, despite thinking I had done it.
hey, maybe check if you got the right username in your remote URL. I faced this issue before and git was trying to auth with the wrong user. run git config --list | grep user to see your details and ensure they match.
Had this exact problem last month - my SSH key expired without me knowing. Run ssh-keygen -l -f ~/.ssh/id_rsa.pub to check if your key’s still valid. Also check your Git host’s security logs - they’ll show auth attempts and helped me figure out my key was getting rejected. Corporate network or VPN? Those can mess with SSH connections too. Try switching to HTTPS with git remote set-url origin https://github.com/username/repo.git to see if it’s a network thing.
