Problem Updating from 2.6 to 2.9

Many thanks tommyligth,  I finally updated to 2.9 by using synaptic manager, and adding some repositories.
However I got this error message  (see Picture)  when trying to run a program, plus axes can´t be moved manually unless I restart linuxcnc.

I couldn´t figure out the cause, so far.
 is anyone willing to give some advice?
