has anyone used more recent versions of ubuntu?
@SmeethRoger_twitter years ago I tried to update Glacier to use Ubuntu 18.04 (instead of 16.04) and found that the setup process required significant changes. On the setup PC, we download the Ubuntu ISO into ramdisk, then write it to the Q1 BOOT usb. Ubuntu got bigger between 16.04 and 18.04 and the 18.04 download wouldn't fit in the ramdisk anymore (on a 4GB laptop). I abandoned the project after realizing that.
