Terminal not working

[Steven M.]

Hello,

I'm using the latest Sourcetree (new installed).

I've set up my SSH client configuration to use my pregenerated SSH key with PuTTY / Plink and all actions within the GUI work as expected.

But when I try to use the terminal, any git operation results in an error:

git fetch
git@hidden: Permission denied (publickey).
fatal: Could not read from remote repository.

I already tried to check my ssh-agent status, but it seems that it is not running or doing anything:

ssh-add -l
Could not open a connection to your authentication agent.

 Any ideas?

Hello Yasin,

Thank you. Setting up SSH Agent did not resolve the issue due to an invalid format. My old key was in format "PuTTY-User-Key-File-2":

Load key "privkey.ppk": invalid format

Opening the key with PuTTY Key Generator and choosing Conversions > Export OpenSSH key (force new file format) did the trick.

Now I have a new key file that can be used within the terminal using ssh-add

Additionally I had to set up a .bashrc for auto-starting the SSH agent upon starting the terminal (for the first time only):

export SSH_AUTH_SOCK=/tmp/.ssh-socket
ssh-add -l > /dev/null
if [ $? = 2 ]; then
    rm -f $SSH_AUTH_SOCK
    echo Starting new ssh-agent...
    eval $(ssh-agent -a $SSH_AUTH_SOCK) > /dev/null
    ssh-add ~/.ssh/privkey.ppk && echo "OK: ssh-agent set up successfully with the following keys:" && ssh-add -l
fi

Now my terminal is working correctly.

Best regards!
