git - Github Authentication Failed - ... GitHub does not provide shell access

Question

$ git remote add origin [email protected]:lut/EvolutionApp.git
fatal: remote origin already exists.

$ git push -u origin master
fatal: 'EvolutionApp' does not appear to be a git repository
fatal: Could not read from remote repository.

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

My keys were added succesfully

 $ ssh -T [email protected]
 Hi lut! You've successfully authenticated, but GitHub does not provide shell access.

The Github article https://help.github.com/articles/generating-ssh-keys/ says that "Shell access" should not be an issue? What could the problem be?

Answer 1

Try and redefine the ssh url for remote origin:

git remote set-url origin [email protected]:lut/EvolutionApp.git

And try again.

Only git remote set-url can change an existing remote URL (as opposed to git remote add, to add a new remote name and URL)
Here, is issue was the URL of the existing origin: EvolutionApp: it needed to be replaced by a valid one.
Using git config url."ssh://[email protected]/".insteadOf https://github.com/ would not have helper, considering there was no HTTPS URL in the first place.
