May be the key that you were trying to add got expired i.e. not available on the server now. Or the key is entered wrongly

Check this link: How do I fix the GPG error "NO_PUBKEY"?

Btw, you can manually delete keys by going into Synaptics.

About mouse. I doubt if it has anything to do with the above error. Check mouse settings in preferences and settings. Something wrong there like pointer speed and acceleration.

Hope this helps.
