This issue can be caused by issues with your SSH agent.

I recently ran into this issue because I changed my default shell from zsh to bash. I'd originally set up my ssh keys using zsh, and so they were not available by default to bash, using chsh -s /bin/bash.

To fix, you'll need to add your ssh key(s) to the SSH authentication agent using the same shell script (bash, sh, zsh, etc) you're using to perform your git commands:

eval `ssh-agent`
ssh-add ~/.ssh/some_key_rsa

You'll need to enter the passphrase for the key in order to add it. To store the passphrase to your user keychain so you don't need to enter it every time the key is used, add the key with the -K option to the ssh-add command.

ssh-add -K ~/.ssh/some_key_rsa

Note the uppercase K as using a lowercase is a different command option.
