As you can see from:
http://ppa.launchpad.net/upubuntu-com/gtk3/ubuntu/dists/

The PPA doesn't support Trusty and should be removed.

if i could see that, then i wouldn't have needed your assistance. there were three selections containing gtk3. in unselecting all, the error messages have not returned. thank you.
