raid517,

As far as your KDE control center problem, I have three versions of KDE and the control center is slightly different in all three, so richenbacherus' idea of booting up your cd and looking at the layout is probably the best idea.

As far as apt-get and dpkg, the commands I use are:

apt-get update #to update the package list using the deb URI's in /etc/apt/sources.list

apt-get upgrade #to upgrade installed packages

apt-get dist-upgrade #to upgrade installed packages and libraries with a version change

apt-cache search #usually used piped to grep ex:
apt-cache search | grep packagename #if you used xfonts for the packagename it would list all packages with xfonts in name or description

apt-get install packagename #install package name (use name from apt-cache output not filename downloaded ex: mozilla not mozilla-1.2.1-0woody1-i386.deb)

apt-get -t testing install packagename #install package from testing depository (or -t stable or -t unstable) used if you have stable, testing, and unstable sources listed (also look into apt-pinning)

apt-get remove packagename ...

dpkg --force-overwrite -i packagename #install package using dpkg when apt-get fails because of dependency errors because a file is listed in more than one package (such as going from kde3.0 to 3.1) Note: using this you have to specify the filename and either be in the directory where the file is or use full path, apt-get save downloaded files in /var/cache/apt/archives.

dpkg --configure -a #will make sure all packages are configured after installation

dpkg -l #will list all installed packages, usually piped to grep if you are looking for a specific package, note packagenames are truncated by default so you may not see the entire packagename

NOTE:
if you get stuck in an apt-get dist-upgrade problem, ie. apt-get dist-upgrade errors out, you will then have to use dpkg --force-overwrite on the packages that are causing problems, once they are installed you then have to go back and run apt-get dist-upgrade again, if it errors out again use dpkg --force-overwrite on the packages that are causing problems, then run apt-get dist-upgrade, repeat cycle until finished. This is NOT needed much, mainly for things like KDE, maybe gnome, etc., multiple package stuff, where a file was in one package in a previous release and now has been moved to a different package in the new release or two different packages contain the same file.

HTH
