<Go Back> does not help. Installation fails trying to download release file from CD

[proebst <proebst@mppmu.mpg.de>]

Hello again,

During an offline install (no ethernet and no dialup connection) from
Etch weekly cd builds, base system installation fails trying to
download the "Release file.

I skipped the step for the mirror selection by using the <Go Back> button to
exit from the mirror selection menue and skipped this step. The next step, the disk
partitioning worked O.K. However the base system installation then failed. The installer
tries to downlowd the relese file and fails. It does not use the release 
file from the DVD.   

Cheers, Franz
