I was trying to install Lightworks 11.5.1 (amd64) on Ubuntu 14.04(amd64) but there's a notice: Dependency is not satisfiable: libtiff4. Is there anyway to solve this dependency issue? Thanks in advance.
Lightworks 11.5.1 is only compatible with Ubuntu 13.10, see the following specs:
Now open a Terminal with Ctrl+Alt+t and type in the folder where you downloaded the deb file:
sudo dpkg -i ./libtiff4_3.9.7-2ubuntu1_amd64.deb
Then try again to open
lwks-11.5.1-amd64.deb with the Software Center to continue the installation.
