Yes, deleted because it didn’t really make sense in the desktop context. But proxmox has a debian derivate unter the hood I think, so everything apart from the DE seems to be fine for you already. That was my point I think. And actually that is what makes the biggest difference with Linux imho, the UIs are pretty standardized these days. Windows, buttons, mouse, unless you specifically want to go fancy. Because you mention web browsing specifically: that is actually the same, isn’t it? Firefox or chromium, not sure how that would complicate things?
