I havent used Mandrake since 9.1 but I believe that you need
to set the sources in rpmdrake. There should be a graphical utility
to do this. You of course set all of your Mandrake disks.
There should also be a directory called /usr/src/RPM/RPMS or
something like that. In this directory will be subdirectories i386,
i486,i586, and so on. You might as well add these too as you can put
downloaded rpm's in there. (blah-blah.i586.rpm goes in i586 and so forth)
Alot of rpm's for Mandrake 10 can be found here:
There is a way to add this sites ftp mirrors to your rpm utility (rpmdrake?)
but I don't know how. Searching this forum will tell you. In the mean time,
You can download packages from the PLF using your browser, copy them
to the i586 directory and install with the drake. (after setting the sources)
I think kopete is part of the kdenetwork package.
