ok i went tot the github and added SSH key after then I tried clone repository again but no success. at this time i received another message

ip@dev1:/media/d1/pr$ git clone git@github.com:/.git
Cloning into ‘’…
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

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

I’m sure that the repository exists but i don’t known which right i should have and if so how to setup them…

could someone point me the what i did wrong and how to fix it ?

The repository URL is missing here. Check the green “code” button on the repository page to find the right URL.

This indicates that the SSH login failed, most likely some issue with the key setup. You can run ssh -vT git@github.com to get debug information from SSH, which should help you figure out what’s going wrong.
