Capistrano Deploy (cap deploy) failing, Authentication errors

Question

I can't seem to get capistrano deploy working.

Here's a bit of background:

The server is currently running, and has a deploy on it that worked successfully yesterday (this was the first deploy I've done).

Today, I wake up, write up a fix for a few bugs, and try to deploy, but I get the following authentication related errors on my Ubuntu box when trying to deploy to my Ubuntu server:

http://privatepaste.com/f774f4b424

I'm using github.

The weird thing is though, I can successfully clone my repo and SSH to [email protected], and it will work and authentication will be accepted. So why is capistrano having such a hard time? I don't really know what to do at this point. Here is my deploy file (which hasn't changed, so should still be working):

I'd really love some help here. Thanks!

Did you enter your server's ssh key on github?

A couple things to try:

if it's just a fairly small app in which you will be doing all the deploys, I would suggest to use the 'forward_agent' option to access the github repo, this will access github using the ssh key on your local machine, removing the need to setup server keys.

ssh_options[:forward_agent] = true
Add the git branch to use

set :branch, 'master'
Try removing the :deploy_via, :remote_cache option, I have had problems with using that with github sometimes.

Hope this helps.

Thanks, but I figured it out. For some reason, it didn't like the way I was tunneling to my development box from work. I was SSH'd into my dev box via PuTTy, and for some reason whilst I'm SSH'd into it from work, cap deploy fails with those errors. I don't understand how or why, but hopefully anyone else having this problem can take this into account as well.
