http://askubuntu.com – Hope s.o. can help me .... According to a page I found I should do this: sudo add-apt-repository ppa:cinelerra-ppa/ppa sudo apt-get update sudo apt-get install cinelerra But that led to the problem that the package "libmpeg3cine" could not be installed because some files were already installed by package "mpeg3-utils". The package system seemed broken because of a defective package. So I tried to uninstall it - which did not work. It worked only by running sudo gedit /var/lib/dpkg/status and removing the "cinelerra" section. Then I tried to compile it according to the g-raffa compilation (HowTos)
