Kubuntu takes over 5 minutes to boot up

[Richard Barmann]

I am using Kubuntu 16.04 and have installed any updates that show up. 
Now I can turn off Kubuntu with the shutdown shown in the drop down menu 
shown in the list of programs . I first close all running programs and 
the do the Power/Session/shutdown. Is this something I have picked up in 
the updates. It was not like this until about 6 weeks ago.

Thank you for any help
