We need updates for the Linux-Version!

With Ubuntu 16.04 reaching EOL in the near future, we need an update for the Linux-Packages to be able to install them on 18.04 or even 20.04. We don't need the features from the newer Versions, we just need official support for Version 11 for newer Ubuntu Distros. Without it, schools here in Europe trying to teach using Linux need to buy more PCs and Windows Licences just for using the Smartboards they already own, which is money that could very well be spend in more important areas. With 16.04 and the old version, everything is working fine, so it would just be updating the dependencies for 18.04.
