avidemux problems with Ubuntu 16.04 LTS

I installed 16.04 a few days ago and had to reinstall some apps. One of them was avidemux. After I installed it from the Software Center, I couldn't get it to work properly. It wouldn't even load a video clip before giving me an error message and closing.

After trying many commands to purge the avidemux files, I still can't get it to reinstall from the Software Center...

Any tips?


I used the PPA : https://launchpad.net/~mc3man/+archive/ubuntu/avidemux1

sudo add-apt-repository ppa:mc3man/avidemux1
sudo apt-get update
sudo apt install avidemux
