not able to clone github repo with ssh

Question

I am using windows 10, with Cygwin (for unix commands), and (git, OpenSSH) from scoop.

Error:

❯ git clone [email protected]:tshrpl/avis.git
Cloning into 'avis'..
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

SSH debug output:

Answer 1

when i run dir in the ~/.ssh folder, i see only 1 pair of key

Then check the public key is registered to your GitHub SSH settings.

You should see there one key with its fingerprint.

Compare its fingerprint with yours (assuming your key is named id_rsa.pub):

ssh-keygen -l -f /path/to/keys/id_rsa.pub

That should be the same considering you do have a Welcome message:

Hi tshrpl! You've successfully authenticated, but GitHub does not provide shell access.

I just tested git clone [email protected]:tshrpl/avis: it does work.

Make sure you have not typed your first git clone command in a sudo (root) session.

The OP tshrpl reports in the comments:

after manually killing the ssh-agent process and restarting it, cloning over ssh works!!
