The latest Avidemux video editor 2.7.1 now can be installed in Ubuntu 18.10 easily via PPA (unofficial) repository.

The new package name has been renamed to avidemux2.7, thanks to Thanh Tung Nguyen. Unfortunately, I can’t build the VapourSynth plugin at the moment due to lack of time (I’m new to computer languages, and one small issue can take me a few hours to solve).

sudo apt remove --autoremove avidemux2.6-qt avidemux2.6-plugins-qt

sudo add-apt-repository ppa:ubuntuhandbook1/avidemux

Type user password (no asterisks feedback) when it prompts and hit Enter to continue.

sudo apt install avidemux2.7-qt5

For Ubuntu 16.04, run sudo apt update to refresh cache first.

Uninstall:
