If you have 2.0 installed now and purchased the 2.1 CD-ROM, you
can run the ``upgrade'' script on the CD-ROM. There are a few
caveats, however. First of all, you should change to runlevel
1 to do this. This can be done with telinit 1 as root. This
will take you off the network (if any) and kill any unnecessary
processes.
You will be presented with a list of config files that have been changed at the end of the upgrade. You may want to move some of them back to their original locations if the formats of the files haven't changed. A quick look at the new one and your old one should reveal whether or not this has happened.
You most likely didn't get the new pythonlib RPM installed.
Install it and it should work again.
If you upgrade your kernel to a 1.3 kernel, you must use ppp-2.2.0. You can most likely find an RPM for this version on your CD or on ftp.redhat.com.
