GIT no such identity: id_rsa: No such file or directory

Question

I create a repository on github and want to push my code, but got the following tips:

$ git push -u origin master
no such identity: id_rsa: No such file or directory
[email protected]: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

But id_rsa file is exist, I tried to add id_rsa public key into my github setting again, and github told me this public has been used.

$ ls
config      id_rsa      id_rsa.pub  known_hosts

this is my .ssh/ folder

config file contain serval git config to different git site. All used the same public key and they could work successfully.

What I did:

$git init
$git add .
$git commit -m "first commit"
$git remote add [my remote git repository address]
$git push -u origin master
// ....  error message

---

UPDATE:

$ git config core.sshCommand "ssh -v"
$ git push -u origin master

Answer 1

For 2 years, IdentityFile id_rsa worked for me. Today, it accepts only an absolute path as in IdentityFile ~/.ssh/id_rsa. Weird thing.

Answer 2

debug1: Will attempt key: id_rsa  explicit
...
debug1: Trying private key: id_rsa
no such identity: id_rsa: No such file or directory

You've configured the wrong private key path. Try configure it like this.

Host github.com
IdentityFile ~/.ssh/id_rsa
