MKVToolNix Gets New Ubuntu Repository Format

MKVToolNix is a set of free and open source tools used to create, edit and inspect Matroska files (.mkv, .mk3d, .mka and .mks).

The MKVToolNix components consit of 4 command line tools:
  • mkvinfo: get information about Matroska files
  • mkvextract: extract tracks / data from Matroska files
  • mkvmerge: create Matroska files from other media files
  • mkvpropedit: modify properties of existing Matroska files without a complete remux

For mkvmerge there's a Qt GUI available, which includes a chapter and header editor. The GUI also implements mkvinfo's and mkvpropedit's functionality and will evolve to cover mkvextract as well.

With the upcoming Ubuntu 18.04 release, repositories that don't use a signed Release file aren't supported by default, so the MKVToolNix developers have changed the MKVToolNix repositories to include Release. As a result, the repository configuration has changed, and if you've previously added the MKVToolNix repository, you'll have to change it.

  • Previously, this is how the repository list file looked:
deb ./
deb-src ./

  • And this is what you'll have to change it to:
deb artful main
deb-src artful main

Replace artful with xenial in the list file in /etc/apt/sources.list.d/ (the file name depends on what you've named it), depending on the Ubuntu version you're using. The repository doesn't support Ubuntu 18.04 Bionic Beaver yet.

How to add the MKVToolNix Ubuntu / Linux Mint repository and install the tool

If you didn't have the MKVToolNix repository added already, here's how to add it and then install the MKVToolNix command line tools and GUI:

  • Ubuntu 17.10 Artful Aardvark:
wget -q -O - | sudo apt-key add -
echo "deb artful main" | sudo tee /etc/apt/sources.list.d/mkvtoolnix.list
echo "deb-src artful main" | sudo tee -a /etc/apt/sources.list.d/mkvtoolnix.list
sudo apt update
sudo apt install mkvtoolnix mkvtoolnix-gui

  • Ubuntu 16.04 Xenial Xerus:
wget -q -O - | sudo apt-key add -
echo "deb xenial main" | sudo tee /etc/apt/sources.list.d/mkvtoolnix.list
echo "deb-src xenial main" | sudo tee -a /etc/apt/sources.list.d/mkvtoolnix.list
sudo apt update
sudo apt install mkvtoolnix mkvtoolnix-gui

There is no repository for Ubuntu 18.04 Bionic Beaver / Linux Mint 19 Tara yet!

MKVToolNix is available for Linux, Windows, macOS and others.
