Why did my Rails spontaneously die?

[meatbites]

I am using Ubuntu 6.06 LTS.

Basically, I had Rails working just swimmingly a few weeks ago. Then the infamous security scare came, along with a patch, and I can no longer use Rails.

Suffice it to say, I can't seem to fix this problem. I have repeatedly removed and newly installed the ruby and rails suite, yet I'm getting nowhere.

I am only just coming out from learning Ruby though, so by 'use Rails' I mean I clicked on the 'About your application's environment' link on a newly generated scaffolding(?) -- i.e.: rails generate/new/site/here. Regardless of how I have set up Rails -- even on a clean install of Dapper -- this link returns an error when I access it via localhost:3000.

Dare I say it -- is this link now not supposed to function? I have not done anything different on my system, other than install the updates as they come down.

When run in super user mode (su ruby path/to/script/server):

Routing Error

Recognition failed for "/rails/info/properties"

Ordinary user:

Application error

Change this error message for exceptions thrown outside of an action (like in Dispatcher setups or broken Ruby code) in public/500.html


All permissions look fine, as far as I can tell. I did have it running fine with Apache, however I am using WEBrick to try and bring it back up.

Speaking of which, in the console it just throws a 404 error in SU mode:

Or a 500 error when just a standard user:

Thoughts on this sudden error? Any help will be greatly appreciated. Even if I can be pointed to an easy to follow guide on gettings Rails running on Dapper.

Just as an update, I seem to have been inadvertently running the original scaffolding creation as super user, so here follows the two errors that probably mean a little more (everything created and run as a standard user).
