This quick tutorial shows you how to install the latest release of MKVToolNix (mkvmerge GUI) and receive future updates from its official repository in Ubuntu 14.04 Trusty Tahr LTS.

As you may know, MKVToolNix is a set of tools to create, alter and inspect Matroska files under Linux.

As the program updates so frequently (almost one release per month), the MKVToolNix version available in Ubuntu repositories is always old. If you would like to receive latest features and bug fixes, using mkvtoolnix repository is recommended.

1. Command Line Way:

If you’re familiar with Linux command line, just a few commands will add the repository and install / upgrade to the latest MKVToolNix release in your Ubuntu.

Press Ctrl+Alt+T on keyboard to open terminal. When it opens, run below commands one by one:

sudo add-apt-repository "deb ./"

wget -O - | sudo apt-key add -

sudo apt-get update

sudo apt-get install mkvtoolnix mkvtoolnix-gui

After that, running regular Ubuntu updates (via Software Updater) will upgrade the app if there’s a new release.
