Permission denied (publickey,gssapi-with-mic) when cloning Git repo

Question

I was cloning a Git repository and I had copied my id_rsa key from another PC to my /home/me/.ssh/ on Ubuntu 12.04, however this error shows up:

Permission denied (publickey,gssapi-with-mic).

How would I solve this issue?

Solution

You shouldn't just copy the key around. Create a new key for the machine you are using in the same way as you created the one you are copying. According to this page, you should do:

1. Create the key

   ssh-keygen -t dsa
   

2. Copy the content of id_dsa.pub file and append it to the target machine's .ssh/authorized_keys file. If authorized_keys file is not accessible, then just create .ssh/authorized_keys2 file and paste the key.

   cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
   

3. Copy the key to the target machine

   ssh-agent sh -c 'ssh-add < /dev/null && bash'

Don't copy the key file directly, use ssh-copy-id instead.

I don't see any authorized_keys under my .ssh folder. should I make it?

Yes, that file has to exist and contain your trusted public key(s).

Ah! I've just realised what you're trying to do. OK, so it looks like you've done the right thing, and your problem might be permissions. Make sure that the keys, and the .ssh directory, are only readable by you.

what about may old ssh key? will I still be use it?

[user962206]

how would I do that?

[Flup]

cd /home/me; chmod 700 .ssh; chmod 600 .ssh/id_rsa .ssh/id_rsa.pub

I just typed the code you have given should I expect any outputs? I tried running git again however the error still exists
