Vanilla OS. I loved the idea of having access to so many packaging formats and package managers at my fingertips but maintaining the system, managing everything and keeping in mind all the things that I'm doing was just too much work for me when I just wanted a system that I can use without any hassle. I know immutable distros are quite the buzz these days but it just isn't for me. That was also the time when I was trying to find an Ubuntu based vanilla GNOME distro
iirc the devs have added Disk Encryption support and it'll ship in the next release (Orchid). I can imagine how confusing and frustrating that must've been!
Maybe I'll give Vanilla OS another try when Orchid releases
