I have installed Cinelerra on Debian 9. I had to activate an additional repository for this, namely deb-multimedia, so that I can install it with apt-get install.
The installation worked and which cinelerra displays /usr/bin/cinelerra as location.
But, something is different than usual. Normally, I can run the newly installed program from the graphical menu, but this time cinelerra can not be found. So I examined /usr/bin/cinelerra and this file is already set as excutable, but I can not run it when I type its name in the terminal ./usr/bin/cinelerra has no effect.
