Hello community! I’m a beginner with git and GitHub. After creating a repository locally, I tried to upload it to GitHub for the first time. Unfortunately, I keep receiving this error message:
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
I’m not clear on what this error means or how to address it. Has anyone faced a similar issue? What might be the reason for this error, and what steps should I take to fix it? I’ve been trying to sort this out for a while and would really appreciate any advice or insights. Thank you!
This error means Git can’t authenticate you through SSH keys - they’re probably not set up right. You can fix this by generating new SSH keys with ssh-keygen -t rsa -b 4096 -C "[email protected]", then adding the public key to your GitHub account’s SSH settings. Or just switch to HTTPS instead - run git remote set-url origin https://github.com/username/repository.git and you can log in with your regular GitHub credentials.
Had this exact problem when I started using GitHub last year. GitHub’s trying to use SSH authentication but can’t find your SSH key. First, check if you even have SSH keys by running ssh -T [email protected] in terminal. If that fails, you need to set up SSH keys properly. But honestly, the easiest fix is just switching to HTTPS authentication instead. When you clone or add a remote, use the HTTPS URL instead of SSH. Then you can authenticate with your GitHub username and password or personal access token - way more straightforward for beginners.
Had the exact same problem when I started using GitHub repos. It happens because GitHub’s trying to authenticate through SSH but can’t find your SSH key. Sure, you could switch to HTTPS like others suggested, but setting up SSH keys properly is worth it - you won’t have to type your credentials every time. After you generate your SSH key pair, run ssh-add ~/.ssh/id_rsa to add it to your ssh-agent before putting it in GitHub. Most people skip this step, but it’s crucial for authentication to work.
i totally feel ya! it’s really annoying when that happens. make sure your ssh keys are set up correctly, or you can just go with the https link instead. it’s much simpler, just pop in your github login when it asks!
yep, i struggled with that too! just switch to https, it’s much easier for newcomers. make sure you enter your username and password when prompted, it’ll save you a lot of headache!
