[Capistrano] Re: Troubles deploying first rails application

[Jamis Buck]

What is the list of files and directories immediately under /trunk in your repository:

  http://192.168.1.4/svn/#{application}/trunk

Is /trunk/public a directory?

The following is the error that is causing the deploy to fail:

But I have no idea _why_ it is causing it to fail. I worked with

and he verified that the directories in question all exist. Has

Dear all,
