Bug#680675: debian-installer: Prompts when InRelease file cannot be downloaded
When installing using debian-installer 20120508 wheezy mini.iso netboot image,
and using a mirror that doesn't support InRelease files (squeeze's version of
approx), during the "Installing the base system" step it prompts with a message
that the InRelease file cannot be downloaded.
Selecting continue seems to work fine, presumably falling back to debootstrap's
handling of old-style Release and Release.gpg files.
It seems like debian-installer shouldn't bother to warn the user at that point
if the fallback methods haven't yet been tried...
