Well, folks… after some two dozen attempts with various methods, I finally got Umbrel booting off of my NVMe drive on PiOS 64 Lite. I then installed via CURL and it shows the full 2TB available, and WOW is it faster than a MicroSD!!!
Now the desktop is saying that version 1.x is available. I see that Umbrel is saying that support for Debian won’t be available until April (which is nearly over), but for those of us who installed already, is there an upgrade we can apply now, rather than wait for the whole OS?
Thanks in advance!
