Hi
I have a problem installing kubuntu 7.04 on a Dell PowerEdge 2500. At a
certain point, the CD can't be read: readerrors and problems with
squashfs.
I googled for the problem, saw that I am not the only one having this
problem, but found no clue.
Perhaps, someone of you gets a clue

Maybe a bad CD?
I had a case recently (on an MSI laptop) where it also had trouble reading
a CD. In that case the drive was not seen at all. No read-errors, because
it didn't even attempt to read, it just dropped me back to a shell.
I noticed that the drive became visible after a modprobe ide-generic.
However, that didn't really help, as there was no (obvious) way to resume
installation. Also, specifying hdb=ide-generic on the grub commandline
didn't help (a similar line helped with SuSE).
So I ended up installing it over the network via PXE
Your case might be different though, as you do get readerrors, and it sees
that there is a squashfs ==> so it manages to at least read _some_ data off
the CD. Which probably means, bad drive, or bad CD.

I've had cases where both CD and drive were "marginal".
The CD would work in other drives.
The drive would read other CDs.
But *that* drive with *that* CD would not work.
The thing is, drive's lasers lose power over time, due to various reasons.
After a while the drive may still be able to read "perfect" CD's, but no
longer CD's that are "slightly" bad. Even if those same CDs pass in other
drives. Nasty stuff.
I've got a gutsy CD like that, that works perfectly with my computers at
home, but that has issues in some other drives (such as our machines on
Linuxfest)
