Update : After several tries Ubuntu starts on my FP3. I loved Meego Harmattan and my N9 I used a FP2 with UT, and liked UT I used LineageOS on my FP3 (I don't like Android) Now using SailfishOS on my XA2 (And love SailfishOS) No I can use UT on my FP3, nice. Next PureOS on my Librem 5 and Sailfish/UT/Mobian on my Pinephone
