SSH cannot authenticate to git@github.com

Recently, I sign up for a free plan on Github.com. I follow their instructions to generate a ssh key to add to my account. However, when I try ssh -v git@github.com, I get this error:

deb开发者_如何学Goug1: Server accepts key: pkalg ssh-rsa blen 277
Agent admitted failure to sign using the key.
debug1: Trying private key: /home/phuongnd08/.ssh/identity
debug1: Trying private key: /home/phuongnd08/.ssh/id_dsa
debug1: No more authentication methods to try.
Permission denied (publickey).

When I look into the error, I see a funny thing here, that is the .ssh/id_rsa was not tried, just .ssh/identity and .ssh/id_dsa were tried.

How can I fix this error? Thanks

You can use ssh-add ~/.ssh/id_rsa to fix this.

Check the file permissions on your key. If they are too liberal it may be refusing to use the key. Make sure they only have perssion for you (0700).

After trying all these answers with no luck, the following command solved it for me:

unset SSH_AUTH_SOCK

If it doesn't already exist, you generate the ssh key first:

ssh-keygen -t rsa 

now copy this key, it'll be in this dir ~/.ssh/id_rsa.pub, open with notepad, paste this key in the "add ssh key" section in your github account! That's it!

If you're using Github enterprise (Self hosting) it would be worth checking to see if the site is reachable. Applies to Github also.

Ran into the same issue in Intellij and when I went to check if the RSA public key was saved in my profile I found out the site returned a server error.
