Hello

I have the following difficulties.

1. I install  kubuntu 10.4
2  I modify the source.list file and follow the instructions from the 
webpage however

I obtain

sudo apt-get install kdelibs4c2a-kde3
Reading package lists... Done
Building dependency tree
Reading state information... Done
kdelibs4c2a-kde3 is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
   libskim0: Depends: kdelibs4c2a (>= 4:3.5.9) but it is not going to
be installed
   skim: Depends: kdelibs4c2a (>= 4:3.5.9) but it is not going to be 
installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or
specify a solution).

try to install trinity?

thanks
