MCE remote issues ubuntu 17.04

Hello all,

after updating ubuntu from 16.10 to 17.04 my MCE remote stopped working with KODI 17.1.
I tried following the sticky about a flawless remote experience and here’s what I found out:

the remote is actually working within the OS, all the buttons are sending the right signals, but within KODI the only working buttons are the directional buttons, nothing else works.

Any suggestion/possible solution would be greatly appreciated.

Thank you in advance.
