i'm using redhat 8 and i need help in upgrading my kde.
so how could this be done?
i'm still new at linux so please take me step by step!!!

go to rpmfind.net and search for kdebase and download the rpm file. then try to install it: rpm -Uvh kdebase.....rpm it will then say that it needs a b and c, so go get those from rpmfind aswell, and add them to the SAME command line as kdebase and keep going until everything installs happily

thank you for ur reply!
but what do u mean by the same command line as kdebase?

and for the kdebase do i download this one?

<kdebase-3.1-0.9.i386.htmlK Desktop Environment - core filesRawHide 1.0 for i386kdebase-3.1-0.9.i386.rpm>

i am using i386 btw

This is how I updated kde when I used a rpm based distro, HTH...

Find out what kde pkgs you already have installed.
rpm -qa kde
Get the equivalent pkgs of the newer version and put them in an empty folder and in that folder create another one specifically for kdelibs and kdebase [...or any pkg you'll need to install individually].

Once you got all the required files d/l'ed, cd to where kdelib and kdebase are and install them , kdelib first, then kdebase.
If it turns up dependencies error but only with the older version of kde, [...like kdelib-3.0.5 is needed by kdexxx-3.0.5] use the --force switch,
otherwise, meet the dependencies first by upgrading the related pkgs.
Then cd ../ to get to the rest of the pkgs and basically rpm -Uvh *.rpm to install the rest in one command, use --force again if required.

Also make sure your actual versions of arts and qt are compatible with kde-3.1. If they aren't, they must be updated first.
