Currently MineOS is based off of jessie. (at least the pre-built ISO on the site says so) I know it doesn’t really matter, but will it ever be updated to stretch? EDIT: I’m a noob that hasn’t done much research so I’m going to assume my post makes not much sense.
The build process I use for Turnkey Linux (what MineOS Turnkey is based on), doesn’t seem to build well with Stretch yet. Tried it last week, and will likely try again soon, hoping the process gets fixed.
