Did this. ls shows nvidia files.

Says no packages found matching <each of the files shown by ls>
To clear it says it can't find any of the nvidia files shown by ls.

The last few lines say: Failed to fetch 
http://extras.ubuntu.com/ubuntu/dist/trusty/Release.  the error is NO_PUBKEY

>   sudo apt --no-install-recommends install nvidia-304*131*deb nvidia-settings_331*deb

Says unable to locate  nvidia-304*131*deb
Says can't find by regrex  nvidia-304*131*deb

So I typed the full name of the file out as shown by ls, still says it 
can't locate it

Just to be sure I typed in the commands you gave me multiple times to be 
sure that there were no typos.

regards, Jim
