How do I install Avidemux On Ubuntu (LXDE)?
I have synaptic but I cannot find Avidemux in it. Should I add a repository to synaptic?
Very easy, run this in your terminal:
sudo add-apt-repository ppa:rebuntu16/avidemux+unofficial
sudo apt-get update
sudo apt-get install avidemux2.6-gtk avidemux2.6-qt4
Edit: The GTK+ packages are not supported any more since the interface does not work. Users should install the Qt4/Qt5 one instead.
avidemux disappeared from repositories after wily; I've resolved adding trusty (because is LTS) repos to my sources.list.
Obviously this installs 2.5.4 version, but the official one; if you prefer a newer one, the ppa method is better.
open a terminal and give:
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
(or choose the filename you prefer) to backup your sources.list
then
sudo vi /etc/apt/sources.list
or nano or gedit or ... the editor you like and add this line on the bottom:
deb http://archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
finally update and install avidemux with
sudo apt-get update; sudo apt-get install avidemux
