> Another Update: Those who want to avoid using an USB thumb drive and are comfortable with SSH can instead do: sudo ln -rsf "$(sudo ls -t1 /media/startos/images/\*.rootfs | head -n1)" /media/startos/config/current.rootfs The OTA update will then work. Sorry for the trouble. A lot of moving pieces here.

Go into GUI and download and update/restart.

Then using SSH and a sudo -i reboot it.
