git remote - fatal: does not appear to be a git repository

Question

Why am I getting this error when my git repository url is correct?

jitendra@JITENDRA-PC /c/mySite (master)
$ git push beanstalk master
fatal: 'git@skarp.beanstalkapp.com/gittest.git' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

You've got the syntax for the scp-style way of specifying a repository slightly wrong - it has to be:

[user@]host.xz:path/to/repo.git/

... as you can see in the git clone documentation. You should use instead the URL:

git@skarp.beanstalkapp.com:/gittest.git

i.e. in the URL you're using, you missed out the : (colon)

To update the URL for origin you could do:

git remote set-url origin git@skarp.beanstalkapp.com:/gittest.git
