Lightworks, newly released to the public as a beta for GNU/Linux depended heavily on the latest packages in Ubuntu GNU/Linux and needed a lot of fiddling to install on Debian GNU/Linux. Recently new libraries were added to Debian Sid (experimental) that makes it possible:
To a minimal installation of Debian Wheezy (I cleared all options in tasksel, but whatever you have will work.)
Edit /etc/apt/sources.list changing wheezy to sid everywhere.
apt-get install apt
dpkg -i lwks (Lightworks .deb file)
If you need an xserver add
apt-get install xserver-xorg-video-whatever... (I used "SSH -Y machine lightworks" from my usual client)
I had a couple of problems. My super strong password wouldn’t work. It doesn’t like lots of symbols… It crashed just idling. There is a memory management problem. Little by little the bugs will be sorted out and this will be a fine video editor for GNU/Linux.
