Hey guys,

So here's the deal...
I'm trying to deploy an app on EC2 using the EC2onRails gem....
I'm using git as my SCM and capistrano to deploy obviously...

Everytime I try to deploy with this command: cap deploy:cold, I get
the following error output on my terminal window:

I just don't know what I'm doing wrong !!!! Wasn't I be supposed to
deploy my app in 5 minutes lol...

Please someone I need help !

This is saying that your ec2 instance didn't have the right
credentials to talk to your github account - either it is using a
public key that you haven't added to the account (either straight to
the account or as a deploy key for the repository in question) or it
doesn't have a key at all.

I've generated a keypair from my instance and copied the public one to
github...
Like you've said, I've put it in the account... didnt work...
I've tried as a deploy key also... without success either...

That's mainly the reason why i'm on this forum right now...

thx for your help....
Still need help though

And you've copied the keys to your ec2 instances (probably also
sensible to setup your ssh config there to tell it to use that key
when talking to github) ?
Have you tried sshing into one of your instances and doing a git clone
from the command line (ie see if it's just capistrano screwing
around) ?

I've tried sshing into the instance and i successfully cloned the
repo...

If the problem is Capistrano... what's wrong in the code above... it
seems perfect to me...

thx again

I think what you want to do is make sure that you can ssh (or git
clone) from the machine (in this EC2 machine) to git so that github's
public key certificate can be added to the known_hosts file of your
"deploy" user (the user that capistrano runs as on EC2 machine) so
that EC2 machine to Github connection is a trusted connection.  I had
no ends of trouble because of this since I forgot to do this.

All that has been done...
I've no problem at all sshing into my instance and cloning the repo
from there...
It seems that the problem would be with capistrano...
