capistrano deployment fails after dreamhost server move

Problem
You have set up your capistrano recipe for deployment to dreamhost using password less logins, but after dreamhost moves your git repository server to a different server, the deployment breaks, with ‘permission denied’ when trying to get the git repository.

Solution
As the server was moved you would need to copy your ssh public key from the deployment server to the new server again for the password-less logins to work again.
Follow the details here how to copy your public key across, login in once with your password, and after that your capistrano recipe should be working again as normal.
