Kitware APT Repository

This is Kitware, Inc.'s third-party APT repository, which we use for hosting our own Ubuntu packages, such as CMake.

We currently support Ubuntu 16.04, 18.04, and 20.04 on our repository. To add the repository to your installation, do the following in order:

1. If you are using a minimal Ubuntu image or a Docker image, you may need to install the following packages:

   sudo apt-get update
   sudo apt-get install apt-transport-https ca-certificates gnupg software-properties-common wget

2. Obtain a copy of our signing key:

   wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | gpg --dearmor - | sudo tee /etc/apt/trusted.gpg.d/kitware.gpg >/dev/null

3. Add the repository to your sources list and update.

   For Ubuntu Focal Fossa (20.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ focal main'
   sudo apt-get update

   For Ubuntu Bionic Beaver (18.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic main'
   sudo apt-get update

   For Ubuntu Xenial Xerus (16.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ xenial main'
   sudo apt-get update

4. As an optional step, if you would like to subscribe to release candidates in addition to production releases, you can add our release candidate repository to your sources.

   For Ubuntu Focal Fossa (20.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ focal-rc main'
   sudo apt-get update

   For Ubuntu Bionic Beaver (18.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ bionic-rc main'
   sudo apt-get update

   For Ubuntu Xenial Xerus (16.04):

   sudo apt-add-repository 'deb https://apt.kitware.com/ubuntu/ xenial-rc main'
   sudo apt-get update

   Note that if you add the release candidate repository, you will still need to add the main repository as well, as the release candidate repository does not provide production releases on its own.

5. As an optional step, we recommend that you also install our kitware-archive-keyring package to ensure that your keyring stays up to date as we rotate our keys. Do the following:

   sudo apt-get install kitware-archive-keyring
   sudo rm /etc/apt/trusted.gpg.d/kitware.gpg

Now you can install any package from our APT repository. As an example, try installing the cmake package:

sudo apt-get install cmake
