Can you post your cobbler rendered kickstart to have a look on it?

I have an install here that I did have previously working with this
hardware and mirror setup however that is now failing for some


reason.  Below is the trace I got back from anaconda, if anyone has
any ideas please let me know :)

Sorry for replying to my own post however I figured that I should
include more information

This is an install with a fairly standard kickstart file (that has
changed) being generated from Cobbler.  Cobbler has just had the RHEL
5.1 dvd reimported into it and this kickstart template tested with
new import and this also fails, where it had previously worked

The install is on to a Dell PowerEdge 1950 III.

If anyone requires any more information about this please let me
if I find a solution I will post back to the list.

Take care.
Cobbler runs through a copy of the DVD tree and identifies the varies
"split" repos and runs createrepo on them.

Having duplicates in the file shouldn't itself be a problem for yum, the
theory was that createrepo might have munged the repo, but seeing this was
an Anaconda traceback I was hoping someone might have better insight as to
how a "None" could get in there.
Hello everyone,

As discussed with Michael on IRC we have found the issue to be with
the duplicate repo lines.  My kickstart template for cobbler currently
has the following line



Michael has confirmed that this is caused by a bug in cobbler that
will be fixed soon.  Anyone who is having this issue should watch the
cobbler mailing list for a patch coming soon.

Take care.

Right, the theory is that multiple repo definitions to the same URL /do/ break Anaconda in certain situations, so we're going to add some basic checks to make sure that doesn't happen.
