I have installed 12.04 xubuntu alternative with whole disk encryption on a machine. I am attempting to set up a schroot usage of backbox 3.01 (an ubuntu 12.04 derivative from what I can tell) under that installation.

When I run debootstrap to install the backbox from the backbox install cd as in:

sudo debootstrap --verbose --arch=amd64 precise /srv/chroot/backbox file://mnt/backbox... (cd path)

I get:

I: Retrieving Release E: Failed getting release file file://media.../dist/precise/Release

The path displayed in the error message I trace to a file that is "Release" and has the release manifest in it, so I am assuming it looks like the target file. I have tried moving the CD contents local and chmod the files to be 777 to make sure there was not some access issue, but still is having the same issue. I have checked to make sure there is no path globbing, or other issue as well.

So a couple of questions.

  1. How do I get debootstrap to work with a CD based installation?
  2. If (1) is not viable, then does anyone know of a online repo I could point debootstap to for backbox (http://)

Write this off as failure to RTFM... The problem in question was a missing "/" in the file:///...

Would be nice if the error message was a bit more descriptive.
