I solved the installation problem myself in this way, using XTerminal, typing: Code: sudo gainroot to become root, then trying to clean up the package system with: Code: apt-get update apt-get -f install the output suggested I should call apt-get autoremove in order to get rid of some illumination-lib, so I did it: Code: apt-get autoremove Now ready to install Khweeteur, this time I did not fire up AppMan but just typed: Code: apt-get install khweeteur Mission successful... no more errors.
sudo gainroot
apt-get update apt-get -f install
apt-get autoremove
apt-get install khweeteur
