RPM cannot be found during installation.

Hi,

During my installation of RedHat Linux 7.2 I got as far as the actually
installing files stage. But the following message popped up:

"The file
/mnt/source/RedHat/RPMS/popt-1.6.3-1.03.i386.rpm
cannot be opened. This is due to a missing file,
a bad package or mad media."

When I switched the 'virtual view' (ctrl+alt 3) to the command shell and
changed to the directory above (/mnt/source/RedHat/RPMS/) the file in
question (popt-1.6.3-1.03.i386.rpm) was definately not there. Although lots
of other RPM files where there.

My problem is the Linux install program is only offering me an 'OK' button
that retries the file -the same message just appears every time I click OK
or press enter. No 'Ignore' or 'Continue Anyway' button is offered. How am
I supposed to proceed?

I tried mounting my cdrom (as the file is definately on the CD and appears
to be fine, not corrupt or anything) so I could manually copy the file
accross but the linux shell won't let me use 'mount' (permission is denied
-despite being root- and another of the virtual views shows mount being set
to -1).

Any ideas what I should do? If 'start the installation again' then how do I
stop this from happening next time as well?

Thanks and regards,

Matthew
