Description of problem:
Upon first time install of Red Hat 7.3 (burned from ISO images) on a system
already containing Linux (Slackware 7.1, but on a completely different disk Red
Hat is supposed to go on), ananconda fails under both graphical as text mode
install with the following Python error message:
Traceback (innermost last):
File "/usr/bin/anaconda", line 503, in ?
from text import InstallInterface
File "/usr/bin/anaconda/text.py", line 28, in ?
from language import expandLangs
ImportError: cannot import name expandLangs
install exited abnormally
The CD has been checksummed and has also passed 'linux mediacheck'. The error
appears just after the X server (succesfully) starts and the Red Hat splash
The error is identical under both graphical and text mode installation.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot from CD.
2. Press either [ENTER] at the prompt, or 'text [ENTER]'
Actual Results: Described above.
Expected Results: Clean install---or at least no error ;-).
This looks like it might be a bad CD burn. Do your CDs pass the mediacheck?
Starting with the Red Hat Linux 7.3 installer (also known as anaconda), it is
possible to test your install media using the installer.
To do this first boot the installer (either from CD or floppy), and wait until
you get a prompt. Then at the prompt type 'linux mediacheck'.
Then answer the first few screens of questions you get, then you will be asked
if you want to test your CD.
It is not necessary to test all the CDs, although this is recommended at least
once. If you only want to test one CD, choose 'Eject CD', then insert the CD you
want to test.
When done testing all the CDs insert the CD #1 and proceed withe the install (if
all the CDs passed, otherwise you will need to get a replacement for the bad

I just tried to run the CD on my laptop (an IBM Thinkpad 600E) where it ran
with flying colours. So apparently my desktop hardware is flawed somewhere, but
in a very subtle and nearly undetectable way, as it acts normally under all
circumstances. Nevertheless, I would appreciate any insights you could give.
Sorry, missed reading that bit... you might try booting with 'linux ide=nodma',
though the kernel should be disabling dma on cdrom devices by default. Also,
we've had people say that just seating the IDE cable better on their CD-ROM
drives has made things work.
