git错误及解决

… but github does not provide shell access

Solution：

Try and redefine the ssh url for remote origin:

git remote set-url origin git@github.com:lut/EvolutionApp.git

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.
