How can I install OpenBoard?

Here is the output of my installation attempt:

Could someone help me figure out why this won't install please? And also tell me what to do to get it working.

  1. I got here because the OpenBoard website proposes that I download the Ubuntu 16 version, but I'm on Ubuntu 18, so when running

    sudo gdebi openboard_ubuntu_16.04_1.5.4_amd64.deb

    I was getting the message:

    Dependency is not satisfiable: libavformat-ffmpeg56

    You can see if that's your case with:

    cat /etc/os-release

    In my case, I'm on Ubuntu 18.

    You can then check the appropriate version on the OpenBoard releases page.

    I downloaded the .deb of Version 1.5.3 for Ubuntu 18 and successfully installed it with:

    sudo gdebi openboard_ubuntu_18.04_1.5.3_amd64.deb

    Oddly, when I open the application it tells me that there is a new version available and it sends me to the official download page where it re-proposes me to download the Ubuntu 16 version. Just ignore it.
