Rails 4 / Capistrano 3 Deployment Stopped Working (no errors)

Question

I built my first Rails app and am running production off a home server. Capistrano 3 worked for about a month and now it just stopped deploying. When I run cap production deploy, my app does not change on the server. It uploads my git-ssh.sh file to the root temp directory, then exits "successfully". I haven't changed anything except modifying some html since it was originally working.

My remote repo is on bitbucket and has the latest commits. I can go as far as commenting out the :repo_url in deploy.rb and not have an error.

Since there isn't an error and since I am a newb, I have a feeling that this is a very general behavior and I have overlooked something small. Any ideas?

Normal Output:

Answer 1

Not that anyone was following, but for the record:

My issue was that I had just set up a github key for other reasons since my last deployment. In doing so, a github_rsa.pub file was created in my .ssh directory. Apparently that made my id_rsa.pub no longer locally known, so Capistrano wasn't sending any of my keys to the server and not getting any errors back.

To fix it, I simply had to run ssh-add to add my key back to my ssh-agent.

Credits go to How to add a ssh key to remote server?, though not completely.
