no logitech remote after upgrade

hi,
my kodi is running on a Intel nuc for years. this morning i started a upgrade from ubuntu 14 LTS to current Ubuntu 16.04.1 LTS
There were no errors or issues during update process and after a reboot kodi came up again like I am used to it.
but my harmony remote does not have control anymore.
No matter what key i am pressing, no reaction in kodi.

please can anybody help me?

thanks,
Markus
