Howdy,

I just installed Linux 9.0 (RedHat) and I'm trying to get stuff up and running. The problem is, I can't install any of the programs I download. I always get the same message, namely:

Installation Tree Not Found.
The path /mnt/cdrom does not look like a valid installation source.

How do I change the install path to the hard drive instead of the CDROM? Thanks for your help!

How are you trying to install the software? Can you read CDs from within Linux?

Damn, I just deleted my response apparently. Well, here goes again.

I'm trying to install software from files that I downloaded from the internet (e.g. Samba). I'm not sure about reading from a CD via Linux, but I did install the OS itself (about an hour ago) from CDs, so I imagine it works. I'll check right now to make sure though.

P.S. Yes, I can read CDs from within Linux.

You already have Samba on the CDs. First port of call when you want to install something new - do I have it on the CDs already?

You need to give more detail. What file did you download? Was it a tarball (.tar.gz) ? Or was it an RPM?

First off, thanks for your help.

Now, I've downloaded both the .tar.gz version (which I unpacked and extracted sans problem), as well as the RPM version. But Samba was just an example. I've downloaded several other programs (things I thought might help), but they all give the same error message, so I think somewhere there's a default path that's set to the CDROM drive - unfortunately, I have no idea how to change it.

One more thing, I just tried to install straight from the CD by going to

/mnt/cdrom/RedHat/RPMS

and double-clicking on the Samba-Client file, but it STILL gave me the same message (Installation Tree Not Found...)

That's pretty bizarre. I don't know what would cause that. If nobody else here knows, try asking in #redhat on the freenode IRC network.

This is just for information because I found many related question about that:
redhat-config-package
I fact the main problem is because this is a buggy tool ! When you are using a simple
CDROM IDE drive, something like /dev/cdrom --> /dev/hdc
or a TRUE SCSI CDROM drive /dev/cdrom --> /dev/scd0
generally you dont get any trouble.(on my own experience)

Serious trouble begins with a IDE-SCSI emulation for an IDE CD/DVD reader /writer
where you are using also the link /dev/cdrom -> /dev/scd0
or you are just using
/dev/scd0 /mnt/cdrom ............... in /etc/fstab

I didn't yet find the bug around solution yet
But if you have some experiment in python language, try to start the RedHat packages manager from:
/usr/share/redhat-config-packages
with : python MainWindow.py
so you can see all the message in the parent shell windows.

A basic error comes when yous are usinf a bad link cdrom under dev
use cdrom --> scd0 (and not cdrom --> /dev/scd0 : in this case you get "unknown cddev scd0)

In fact all the preliminary check is done in the method.py:
ERRORS like:
"unknown cddev ..."
or
"The path /mnt/cdrom does not look like a valid installation source" come from it
(I found related trouble with Fedora, but I don't have experienced by myself )
----------------
I continue to search ...

Sorry the trouble is not related to the IDE-SCSI emulation, but to the installation process
in RH9.0

In fact on all the machine where I migrate from RH 7.X ( I experienced RH7.3 and 7.0) directly to 9.0, I experienced no problems.
Only on the machine where I Installed directly RH9.0 from scratch I got problem ( the one with my CD/DVD writer )
I finally found the good explanation here: https://bugzilla.redhat.com/bugzilla....cgi?id=116107
IF YOU HAVE NOT the comps package INSTALLED YOU GET TROUBLE
--> check with:
# rpm -qa | grep comps
in good situation you must have:
comps-9-0.20030313
comps-extras-8.0.94-1

If comps-9-0.20030313 lacks then install it:
So Just mount the CD1 of RH9.0 (Shrike)
go under /mnt/cdrom/RedHat/base
and install it with:
# rpm -i comps.rpm

Then restart the redhat-config-packages from shell or from main destop menu as usual
