Comment 9 for bug 347458

I suggest a cron job for opening this bug over and over again for
every ubuntu release (including betas and rc's). :)

That was a joke and here is soultion, that helped me numerous times
during installation of at least 3 different Ubuntu releases (8.10,
9.04 hits this bug even in a release, 9.10)

Make a change to cdrom detection script, which is (i believe)
/var/lib/dpkg/info/cdrom-detect.postinst

there is a line in it like

if db_get cdrom-detect/try-usb && [ "$RET" = "true" ]; then

in this line "&&[ "$RET" = "true" ]" should be removed and then
everything goes OK.

Actually upon loading alternate install cd one of my first actions are
to switch to another console, edit the file
/var/lib/dpkg/info/cdrom-detect.postinst and then proceed as usual.
This always worked.

I am not sure about any regressions though (e.g. to other installation usecases)

> This results in the "No common CD-ROM drive was detected." error.
