Here's my Capistrano file:

role :app, "192.168.1.1" # This may be the same as your `Web` server
role :db, "192.168.1.1", :primary => true # This is where Rails migrations will run
The IP addresses above are obviously fake, I'm using the IP for my VPS
server in real life.
I ran this command, to verify that BitBucket is allowing me to access the repository:
sergiotapia#jarvis1:~/.ssh$ ssh -T hg#bitbucket.org
conq: logged in as sergiotapia.
You can use git or hg to connect to Bitbucket. Shell access is disabled.
However, running cap deploy again, I get:
[198.211.101.99] executing command

I tried using git clone from my SSH terminal, manually and it worked fine as expected. My project cloned to a folder properly.
It seems Capistrano is running sudo git clone instead of git clone. This is verified by myself running a sudo git clone in the same folder manually on my SSH. Same Permission denied (publickey) error.
Why isn't my Capistrano setting for :use_sudo, false being used?

I've been looking at a way to deploy my app using capistrano. I currently am hosting a small private repo on github and a local server to try deploying my test. I come upon a problem and an error message below.
I have done the following
Generate an ssh key on server and added it sucessfully to deploy keys in repo and tested(git#github.com)
Generate an ssh key on client and add it sucessfully to deploy keys in repo
setup a private repository. And have account deployer with rights to deploy
configed deploy.rb and production rb to follow mimic many other templates out there.
I still cannnot figure why it is giving me an error like this

I had a similar problem. It turns out that the SSH agent was not running. I found this out looking at the Capistrano documentation: http://capistranorb.com/documentation/getting-started/authentication-and-authorisation/
Running this command:
$ ssh-add -l
showed me that my public key was not added to the agent so I had to add it:
$ ssh-add
Identity added: /Users/me/.ssh/id_rsa (/Users/me/.ssh/id_rsa)
After this my Capistrano deployment worked.
You should set in production.rb:
forward_agent: true
I was having the same problem with Capistrano 3.4. With Capistrano 3.2.1 it seemed to ignore this parameter.
You can use capistrano-ssh-doctor to troubleshoot possible config problems.
I think your capistrano may have some old files in its git cache, probably from renaming the repository or something like that. Try to delete the cached-copy folder in the shared folder on the server, so capistrano will pull your repo again.
I am modifying a functional Capistrano script trying to speed it up since my home internet upload speed is horrendous. I have a git server (not github), and a ubuntu dev server, when I run cap deploy it currently grabs the latest from my git repo and makes a local copy then uploads that to my ubuntu server and restarts passenger without an issue. My capistrano code contains...
set :deploy_via, :copy
But if I try to use this instead...
set :deploy_via, :remote_cache
I get this error...

It prompts for the git password - gitadmin#sub.example.com's password:
which I enter and it proceeds ok, then it seems to error out on the next command above. I'm guessing I need to setup some ssh keys somehow? Again this is not hosted on github, the repo and dev server are two separate boxes on my company servers. Locally I am running windows 7. If I try adding...
set :ssh_options, { :forward_agent => true }
default_run_options[:pty] = true
I get the same distance but this time instead of automatically saying permission denied, it prompts for the gitadmin password, I enter it correctly and it says "permission denied".
It would help if you posted your full capistrano scipt (minus any passwords, ip addresses) but I suspect that you need to introduce your server to the remote repository.
You don't need deploy_via option at all
To introduce your server to your repo ssh into your server and from there ssh into the repository service, there should be documentation on the url to use for this. You would get a access denied message but the point is that this process adds ssh public key to your server
It might also be worth watching Ryan Bates Railscast on deploying, he uses github but the process is pretty similar for any remote repo
http://railscasts.com/episodes/335-deploying-to-a-vps
Pay attention to how he introduces his server to github, like I say, your service should provide you with instructions for similar introduction
There is a revised (pro) cast that you would need a subscription for but Ryan is on an extended break (possibly indefinitely right now) so a subscription would be extremely good value right now and well worth thinking about.
The revised (pro) cast on capstrano, how to set variables etc... is here http://railscasts.com/episodes/133-capistrano-tasks-revised
This is a working script for one of my apps just replace xxx and paths as you see fit, I assume you have all the start and restart stuff already set up but this should point you to at least the minimum settings needed. I say this because you possibly have other setting that you don't need, but as you haven't posted your script it is impossible to tell.

I'm using the Capistrano gem and this tutorial to deploy my application to my remote server. Everything works fine until the end of the cap deploy command. I'm receiving this error:

What is going wrong?
It's hard to say exactly, but it's clear that your releases/#{revision} dir is missing by the time you try to push the git revision into the file REVISION.
One likely issue that should probably get fixed is your :deploy_to dir is the same directory on the same machine as the git repo you are cloning from. Try this instead:
In your deploy.rb
set :deploy_to, "/home/#{user}/app/#{application}"
Then make sure to run this the first time:
cap deploy:setup
Then feel free to:
cap deploy
After a lot of head scratching, oddly enough, it was cap deploy:setup that was my downfall. I am still unsure as to what was going on, but I have thoroughly tested and verified that deleting the deployment directory and redeploying the application without running cap deploy:setup will work.
For some reason, running cap deploy:setup, even after successful deploys, will cause permission errors and causes cap deploy to be unable to create and write to directories.
I'm trying to deploy an app to an amazon webserver. I have git installed and functioning (I already successfully made a push. But when I try to do cap deploy I get "permission denied"
Here's the error:

Probably a silly time to ask, but I'm wondering if I need to already have ruby and rails installed for this to work. I'm going to do it right now anyway... but I was just wondering (didn't know if cap does it for you.)
But other than that..why would it be failing?
Again git is setup and running fine. Push worked just great. SSH is working fine. Another thing I should note is that I tried it both with running ubuntu#22.229.78.34 and with just running 22.229.78.34. I did it the ubuntu way because that's usually the only way amazon will accept a connection. Any help would be appreciated.

Looks like you need to forward your Github ssh key through the ssh connection Capistrano opens to the AWS instance. Add set :ssh_options, { :forward_agent => true } to your deploy.rb
