Permission denied (publickey,gssapi-with-mic)

Question

I am trying to connect to a VM using this command:

sudo ssh -i /home/ritesh/.ssh/id_rsa1 [email protected] -L 5901:localhost:5901

But it's giving me this error:

The authenticity of host '54.80.22.15 (54.80.22.15)' can't be established.
RSA key fingerprint is X.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'XX.XX.XX.XX' (RSA) to the list of known hosts.
Permission denied (publickey,gssapi-with-mic).

How do I resolve this error?

Solution

you need to copy your public key to VM, it's not recognized your public key so add it

$ scp ~/.ssh/id_rsa1.pub [email protected]:.ssh/authorized_keys

or also try it

$ cat ~/.ssh/id_rsa1.pub | ssh tc@[your.ip.address.here] "cat >> ~/.ssh/authorized_keys"
