I'm using a RH Linux 7.2 PC. Unfortunately it doesn't come with KDE.
I have downloaded KDE 3.1 from www.kde.org and burnt that into a CD-R.
Next I try to install the rpm from the CD into the computer. These are what I did:
1)rpm -ivh qt*.rpm (this step is ok)
2)rpm -ivh kde*.rpm (erroros follow)
3) the error message is something like this
expected 1476336
actual 642386
cannot unpacked archive......
4) the installation continues and it shows 100% for all the kde rpm

Ok, then I try to search for kde at /opt but I cannot find it. I suspect that kde was not installed properly.
Any advices?

By default kde isn't installed to /opt.
I'd try to run kdm to see if it installed ok.

Hi,
How to run KDM?

To test kdm and kde:
log in as root in a bash shell
enter kdm
