There are plenty of posts over internet (primarily quite aged) that suggests how to get minimal/lightweight/minimalistic KDE Plasma desktop on top of Ubuntu Server. For example, minimalistic means there is no need for bluetooth stack, fancy fonts or thunderbolt devices mgmt (that are all inscluded if to install kde-plasma-deskto).
But maybe someone here has cloud-init script for the implementation with all the caveats covered?
Background - a number of cloud providers don’t allow import of custom ISO as valid OS image for the VM. For example, digitalocean doesn’t allow it, however vultr does.
But both do support cloud-init scripts.
Just in case, kde-plasma-desktop by itself is not a complete solution, as it pulls bluetooth stack, fancy fonts or thunderbolt devices mgmt and many others.
