Linux Question

Permission denied (publickey) when trying to Git Clone

I know this is a common issue, however, even after spending an hour looking at threads I was unable to find a solution and therefore am posting here. Basically, when running

git clone
, I am getting the following error:

Permission denied (publickey).
fatal: Could not read from remote repository.

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


I do have a id_rsa and a id_rsa.pub in my .ssh directory, and the key matches up with the key I have on github as well under the ssh keys section. So that's not a problem. However, I realized I don't have a id_dsa file or any other file for that matter (except a knownhosts file). When running

ssh -T git@github.com


I get Permission denied (publickey).


When running
ssh -vT git@github.com
, I get:

Something is weird but I can't quite figure out what the issue is. I have my keys set up using the GitHub documentation, but am still getting a permission denied statement. My keys are the same, as I checked my key on Github and made sure that the numbers are the same when running
~/.ssh$ ssh-keygen -lf ~/.ssh/id_rsa.pub


Any help would be much appreciated!!

Answer

The key is rejected obviously. Run

ssh-keygen -y -f ~/.ssh/id_rsa
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDHFxArGbqkeamciLR8kcsCwFYnagqNe/XG1Ehqhq092mwd/xHq89Pf1kVvC3OBOrvnb4g9l4LMKH28d8ZSJ2cDvtVwolMZBMzNB5HKid+7fNARQngY8t/WE+0ZuQjsA6OelgVx7QYBz893+0gKXdpALxs2Hd69s6Oy+vGphHmxsKG9PHe7l5StJBhMGbBTwDPcO/2YuZE7g5mh3VL/i3EfmkdYLBlBz1FD7/2J8npoYSdiGxUWvrbawfUw8fQwR6byM5AXBHWgJfWyGLKP6etvSQVTdutrp0GBjWn5GFlw8pKsb3R3N6h8CVKHKDAa4Hrf8wduOTwgT22n4zQ677Np

and verify that the string is the same as what you have stored in your github account. From the last update it looks like you stored there output of

ssh-keygen -lf ~/.ssh/id_rsa.pub
2048 SHA256:xh0IVbIJmeYwdFWnvDQp/hB4OK+mjhlPyVXYQVpHTIA jakuje@jakuje-PC219 (RSA)

or

2048 MD5:46:e0:1e:c4:7f:de:12:66:ff:28:e6:36:81:cd:a8:b4 jakuje@jakuje-PC219 (RSA)

which is not the public key, but only its fingerprint (it is not enough). You need to store in your github account whole public key -- content of the file ~/.ssh/id_rsa.pub.
