Question

I'm unable to clone any repo from github using SSH. Here are console outputs:

root@local-machine ~#  git clone [email protected]:getify/You-Dont-Know-JS.git js
Cloning into 'js'...
[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.

What I'm doing wrong? Thanks

Answer 1

What I'm doing wrong?

1. Unless your have a good reason, your first error is probably to checkout a github repo logued in as root on your local machine instead of your normal user.
2. Have you declared your rsa public key on github GUI for your account (click on your picture > settings > SSH and GPG keys) ? The repo your trying is public so there should be no other requirements to clone it through ssh than being known to github.
3. If you have declared a key, are you sure you did not use your personal account public rsa key instead of the one used by root (which comes back to point 1) ?
