Hi wasserfloh,

  The problem is about your git configuration. When capistrano
executes it in remote server:

   /home/oag/oag-server/shared/cached-copy && git checkout  -b deploy
aeba71d5b7ce45e24cdb2bf052260fbc235b3a66; fi"
    servers: ["oag-server"]
Password:
    [oag-server] executing command

  The output is it:

 ** [oag-server :: out] Initialized empty Git repository in
/home/oag/oag-server/shared/cached-copy/.git/
 ** [oag-server :: err] Host key verification failed.
 ** [oag-server :: err] fatal: The remote end hung up unexpectedly
 ** [oag-server :: err] fetch-pack from 'o...@oag-server:git/wvz.git'
failed.


  Connect to your server and try to do a checkout, I guess you will
get same error.

Regards

PS: Sorry, I'm not a git expert so I can't explain the steps to
configure git :S
