Ah! I'd missed that you were upgrading! I thought you had a different
desktop. Sorry for this, also sorry about the delay in replying, I blame
the timezones.

Well, if you've removed the old ones, they're gone. If something needs
e.g. libxyzzy >= 1.0 and you offer it libxyzzy 2.5 it "ought" to work,
but the 'dependent applications' either got removed (-e app3 etc) or you
took a risk with -nodeps (your follow-up mail).
What you need to do is
(a) list what will be broken (autorun, 3d-screensavers, everything)
(b) list what is in each of these packages [rpm -ql]
(c) decide if they matter to you
(d) if they do, check the kde2 packages have a replacement.
I'd particularly make sure you have the kdenetwork package available if
you are using kppp to dial out, and also that you've made a note of the
settings to connect to your ISP.
>From memory, when I was trying to upgrade to kde2 (beta) from kde1 my
process was
1. back up the data, e.g. mailboxes if you use kmail.
2. copy all the kde1 and other affected rpms to somewhere safe, so I could
back-out.
3. remove each package individually, taking time to find a sequence that
avoids playing with 'nodeps' or other overrides. (ok, there might be a
loop with kdelibs and kdesupport that requires -nodeps)
4. install kde2 packages using the inverse sequence to '3'.
and in my case
5. remove the kde2 beta packages, because kmail wouldn't run
6. reinstall the kde1 packages
7. restore the data.
Yes, it was a pain, but the overall apply/test/backout-if-necessary
process worked on the 2 occasions I tried it. In the event, I had to
install an upgraded distro because the hard drive failed, and the distro
(Mandrake 7.2) came with a functioning set of packages.
Which reminds me, if you have 64Mb or less, you may find the performance
of kde2 is not acceptable. The classic gotcha - if you want something (in
this case koffice) you have to use suitable hardware.

looks like qt2 is installed, then. I think the intention of changing the
names was so that developers working on qt2 could have a working version
of qt1 to fall back to, but I could be wrong.
You're going to need plenty of time and coffee, but you will learn a lot
about life, the universe, and rpms. (grin)
