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 consists 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 https://mkvtoolnix.download/ubuntu/bionic/ ./

deb-src https://mkvtoolnix.download/ubuntu/bionic/ ./
  • And this is what you’ll have to change it to:
deb https://mkvtoolnix.download/ubuntu/ bionic main

deb-src https://mkvtoolnix.download/ubuntu/ bionic main

Replace bionic 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.

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:

sudo apt install mkvtoolnix mkvtoolnix-gui

Update: initially there were no repositories for Ubuntu 18.04 Bionic Beaver / Linux Mint 19 Tara and newer Ubuntu versions, but they were later released, so I added instructions for this new Ubuntu / Linux mint version to the article.MKVToolNix is available for Linux, Windows, macOS and others.
