How to Install Avidemux in Ubuntu:

For Ubuntu 16.04, Ubuntu 17.10, Ubuntu 18.04, you can install the new Avidemux packages via the unofficial PPA.

Sorry that the package names are still avidemux2.6 due to lack of time and my poor language skill.

1. To add the PPA, open terminal either via Ctrl+Alt+T or by searching for ‘terminal’ from app launcher. When it opens, run command:

sudo add-apt-repository ppa:ubuntuhandbook1/avidemux

Input your password (no visual feedback while typing) when it prompts and hit Enter.

2. Then install avidemux2.7-qt5 package either via Synaptic Package Manager or by running commands:

sudo apt-get update

sudo apt-get install avidemux2.7-qt5 avidemux2.7-plugins-qt5

Uninstall:

For any reason remove the software via command:

sudo apt-get remove --autoremove avidemux2.7-qt5 avidemux2.7-plugins-qt5

To remove the PPA, launch ‘Software & Updates’ utility and navigate to ‘Other Software’ tab.
