RedHat's fix for the Anaconda crash doesn't work on my machine. You recommend three things (verify the files aren't corrupted, eliminate the non .rpm files, and use the new install boot disk). I've done all three and the only change, after a lot of time is that the error message after Anaconda/Python crashes the install changes. It initially was "unsubscriptable object" and now it's "sndconfig".
If you are no longer getting the error about "unscriptable object" then the fix that we provided did indeed work. What error message are you getting now? Submit those details and we will work to replicate in the test lab.
Anaconda is the installer itself. I said that the first fixed worked because it did. By getting rid of the non-rpm files in the RPMS directory, you are no longer getting the "unscriptable object" error. This is because you no longer have an unscriptable object. I really need the error message that you are getting relative to sndconfig. There could be 100 different error message that you are receiving. These range from the installer not being able to find the sndconfig package in order to installer it to the installation of the sndconfig package failed when the installer attempted to place it on the system. I have no record of anyone reporting an error related to sndconfig, so therefore I need some context for this error, otherwise there is no chance that I am going to be able to replicate this situation in the lab.
