"Could not open a connection to your authentication agent"

ssh-agent.md

SSH authentication agent does not automatically start when using it from a remote server. This results in the following error message:

$ git pull
Permission denied (publickey).
fatal: The remote end hung up unexpectedly
$ ssh-add ~/my-ssh-key.pem
Could not open a connection to your authentication agent.

To fix it requires manually starting ssh-agent:

$ eval `ssh-agent -s`
Agent pid 13442
$ ssh-add ~/my-ssh-key.pem
Identity added: /home/user/my-ssh-key.pem (/home/user/my-ssh-key.pem)
$ git pull

I am new to all of this and want to ensure I am understanding the syntax. The '~/my-ssh-key.pem' what is this value? Or do I use that in the CLI when attempting to rectify this overall issue?

That is your SSH private key. Make sure you give the command ssh-add the correct path to where your private key is located on your filesystem. By default, this file is usually in the ~/.ssh/ directory and is called id_rsa or id_ed25519.

This came in clutch, Thanks!

SSH_AUTH_SOCK=/tmp/ssh-WvEP0dKfXLyl/agent.1753; export SSH_AUTH_SOCK;
SSH_AGENT_PID=1754; export SSH_AGENT_PID;
echo Agent pid 1754;

if i try adding the key again
it returns "could not open connection to your authentication agent.

Perfect for me, thank you!

Thank you very much for your contribution @mvneves

I use access via VS Code, does anyone have a solution so that when I load VS Code it ​​already runs these commands?

I tried .bash_profile and other approaches but without success.

Do you have any examples?
