Capistrano users, if you've ever updated your project's Git repository and tried to deploy, you'll see an error message similar to:
[IPADDRESS :: err] conq: repository does not exist. [IPADDRESS :: err] fatal: The remote end hung up unexpectedly
This occurs because the cached copy points to the old repository.
To fix this, manually delete the
cached-copy folder. Don't worry, it will be re-created on your next deployment.
