Just wanted to add that I ran the updates and they did not resolve this issue

The problem has been coming and going I tried loading old kernals which didn't fix it.

Can someone help me get the symbol libraries installed.

I never fixed the missing key issue but my problem was on this line of code

apt-cache policy yelp

I was coping it verbatim instead of changing yelp to the program I was having trouble with (evolution in my case)
