pasos de ssh
https://help.github.com/articles/generating-ssh-keys/

luego git clone ssh repositorio,  SI LO HACES DESDE HTTPS TE PEDIRA CONTRASEÑA ALL TIME

En ~/.bashrc debe poner:

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

if [ -f ~/.bash_prompt ]; then
    . ~/.bash_prompt
fi

los archivos van dentro de home/user
en debian: instalar curl (que es un cliente http para la consola) y rvm
rvm: seguir las instrucciones de
http://rubyonrails.org.es/instala.html

si te has copiado las llaves ssh de otro ordenador les pueden faltar los permisos.
Hacer chmod +600 ~/.ssh/*
y luego probar con ssh -v [email protected] para ver si te devuelvt un you ve succesfully authenticated
