GIT no existe tal identidad: id_rsa: no existe tal archivo o directorio

Creé un repositorio en github y quiero enviar mi código, pero obtuve los siguientes consejos:

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

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

Pero el archivo id_rsa existetraté de agregar la clave pública id_rsa en mi configuración de github nuevamente, y github me dijo que se había utilizado este público.

$ ls
config      id_rsa      id_rsa.pub  known_hosts

este es mi .ssh/ carpeta

El archivo de configuración contiene la configuración de git de serval en un sitio de git diferente. Todos usaban la misma clave pública y podían funcionar con éxito.

Lo que hice:

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

ACTUALIZAR:

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

Configuró la ruta de clave privada incorrecta. Prueba a configurarlo así.

Host github.com
IdentityFile ~/.ssh/id_rsa

Por 2 años, Archivo de identidad id_rsa trabajó para mi. Hoy, acepta solo un camino absoluto como en Archivo de identidad ~/.ssh/id_rsa. Cosa rara.
