This is Kitware, Inc.'s third-party APT repository, which we use for hosting our own Debian packages, such as dh-cmake and nightly builds of VTK.
We currently support Debian Sid on our repository. To add the repository to your Debian Sid installation, you will first need to obtain a copy of our signing key:
sudo apt-key adv --keyserver pgp.mit.edu --recv-keys 461FD00B2DB57A2D
Alternatively, you can obtain the key directly from our website:
wget -O - https://apt.kitware.com/keys/kitware-archive-2018.asc 2>/dev/null | sudo apt-key add -
Finally, add the repository to your sources list and update:
sudo apt-add-repository 'deb https://apt.kitware.com/debian/ sid main contrib' sudo apt-get update
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 apt-key --keyring /etc/apt/trusted.gpg del 461FD00B2DB57A2D
Now you can install any package from our APT repository. As an example, try installing the dh-cmake package:
sudo apt-get install dh-cmake
