Hi @raphael68 !
Yes indeed UBports is working fine on my FP2 
As I already mentioned here, I had trouble with the UBports-installer so I used the CPT alternative installer.
Do you have a recent FP2 (shipped in or after summer 2017) with the new screen ? If this is the case, you’ll have to install the devel channel as the fix are not yet pushed to stable OTA-2… (or wait for OTA-3 as it will come soon )
If you need any help the UBports community can help you on their Telegram group !
