First - let me say that I think the Teracube is pretty thoughtfully designed. I just wanted something simple and secure, that will last a long time (my last phone was a flip phone that gave me a decade of service!). Teracube seems to have the right ethos…
I have a few reflections on /e/ OS - this seems like it could be a bug.
First, a note for the Teracube team: I paid for an advance replacement to my (Android) phone because of a cracked screen, but the device I received back had eOS 0.17 on it. I suspect a lot of customers who are used to Android would be thrown off by this, and might complain. I, however, was delighted - my plan was to install LineageOS on the new device anyway. Close enough (and maybe better!).
It works quite well! There’s only one thing that’s happening that I’m unsure about. When I look at updates, there’s a list of updates from 0.17 up to the most recent 0.20. It seems I need to manually download and install. When I hit install, I see
You are about to upgrade to /e/OS 0.20 - Dec 15, 2021.
If you press OK, the device will restart itself in recovery mode to install the update.
Note: This feature requires a compatible Recovery or updates will need to be installed manually
This leads me to believe it might be a bug. It seems like I might need to manually flash the device and start fresh?
