Github permission denied: ssh add agent has no identities
This is my first time accessing GitHub and I'm not experienced using a console. I am on a MacBook using Bash. When I try to access GitHub, I get this:
git clone [email protected]:dhulihan/league-of-legends-data-scraper.git
Cloning into 'league-of-legends-data-scraper'...
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
I've tried following the instructions on Github page about permission being denied.
When I use ssh -vT [email protected], I get the following:
OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011

Permission denied (publickey).
Next, eval "$(ssh-agent -s)" returns "Agent pid 2314",
however ssh-add -l returns "The agent has no identities."
And that is where I am stuck.
Answer
Full details in this answer.
In summary, when ssh-add -l returns “The agent has no identities”, it means that keys used by ssh (stored in files such as ~/.ssh/id_rsa, ~/.ssh/id_dsa, etc.) are either missing, they are not known to ssh-agent, which is the authentication agent, or that their permissions are set incorrectly (for example, world writable).
If your keys are missing or if you have not generated any, use ssh-keygen -t rsa, then ssh-add to add them.
If keys exist but are not known to ssh-agent (like if they are in a non-standard folder), use ssh-add /path/to/my-non-standard-ssh-folder/id_rsa to add them.
See this answer if you are having trouble with ssh-add or ssh-agent.
