I updated my Slackware from 10.0 to 10.1 with slapt-get and my KDE broke down.
KDEINIT is missing / or something.
And some of KDE apps wont work too.
kmix: error while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory
Since this might have deleted/edited/changed current configuration, you might want to update/re-install your KDE environment...
KDE 3.3 is out and stable and available here
Hope this helps
The exact same thing happened to me. What I had to do is reinstall the old version from the CD. Take your CD I think it is the second one mount it in a command line
ls # this will give you a list of what is on the cd you are looking for something like kde.tgz if you don't find it look on the other disk
once you locate it
cp kde.tgz /usr/local/src
installpkg kde.tgz # this is the only command needed it will install itself
shutdown -r now # this reboots system.
This should get you back to the old version and you can keep trying to upgrade and go back and do this again or live with the older version (which I do)
Let me know if this is not clear. Hope this helps
I screwed little bit more, so i had to reinstall linux.
But thanks for advice, hope somebody gets info about this post :)
