[Capistrano] Re: svn checkout host key validation error, Amazon EC2

[Jamis Buck]

I've afraid I've never had that error, so I'm not sure. :( Anyone else have any ideas?

Thanks for the quick reply Jamis. I've created a keypair on the
instance and copied to the "jason" account on foo.bar.com.  Now
regular ssh from the shell to foo.bar.com works:

[EMAIL PROTECTED]:~# ssh -i ~/.ssh/id_rsa
[EMAIL PROTECTED] hostname
foo

Then I went to run the cap task again but got the same Host Key
Verification error again. I thought maybe I needed to put my username
in the URL, so I changed the :repository value in my deploy.rb to:

set :repository, "svn+ssh://[EMAIL PROTECTED]/svn/#{application}/code/
ror/tags/quez/12"

...then ran the cap task again but nothing changed, same error. Any
other ideas?

Thanks again for your help!

I'm not 100% sure what the "host key verification failed" error is
about, but I suspect it is Subversion's SSH connection complaining

to. Regarding passwordless authentication, you'll need to make sure
that you have your keys set up such that you can ssh from the EC2
instance to your "foo.bar.com" server (the one hosting your svn
repository).

I'm trying to deploy my application on an Amazon EC2 instance running

Ubuntu. I have a keypair set up and can log into the instance using

instance until I try to do an svn checkout:

ssh just fine. Matter of fact, all my capistrano tasks run fine on the

(I've edited the output for brevity.)

I get "Host key verification failed", so I log in to the instance and

try to execute the command manually to see what the problem is:

[EMAIL PROTECTED]:~# svn checkout -q  -r2048 svn
+ssh://foo.bar.com/svn/baz/code/ror/tags/quez/12 /mnt/app/releases/

REVISION)

capistrano from working. My question is, how do I get the instance to

Any & all advice is appreciated- thanks!
