@ann_droid LineageOS instructions are "boot into fastboot, ensure the bootloader is unlocked, flash the TWRP recovery on, boot into TWRP recovery, copy the LineageOS zip and the gapps zip over if you want that, and then select the zips inside TWRP to flash to the device." I don't know what it's telling you to "re-enable USB debugging" for, but whatever it is, is something that assumes you're running Android. You don't need to mess with that.

Thanks, I will give all of it a try. Let you know what happens. Are there images that you can get and load?

@gucu No sorry your device is not supported this is the current list of supported devices https://devices.ubuntu-touch.io/ Due to the nature of Ubuntu Touch each device has to be ported separately and takes a lot of work and effort. There should be other device available later in the year but no clear time scale yet.
