update problem.

[Bob]

I am trying to update my Kubuntu 18.4LTS and I get an error message that 
is on and off the screen so fast I can't read it.
   says something about E:dpkg  but can't catch what I am supposed to do to

I downloaded apachi2 for a friend and this is when it started.  I had 
planned on deleting apache2 since I have no use for it and it is kinda big 
but have no idea what may have happened. if it would stay on the screen 
long enough to read it would probably be something simple but not knowing 
what issue is frustrating

any ideas??   I don't think I have ever messed with dpkg and why the E: 
makes no sense.
   what I have runs normally and I have tried rebooting but no effect.

??????
thanks
Bob
