“Most desktop Linux distributions are oriented towards tech-savvy users and developers, but Endless OS isn’t your typical Linux distribution. We have a different target user. We don’t use rpm, apt, or any other packaging system. We use a read-only root file system managed by OSTree with application installed using Flatpack”
Yeah, now it’s unable to Install VMware Tools to view in full screen, or copy-paste between Windows and Endless. So this prevents it to use this this OS.
