Requires installation of untrusted packages

I know I got trouble updating Quantum GIS patch files in the Ubuntu computer because recently it gave the above message. I sought the help of my son who likes to tinker in Open Source and Ubuntu where he recommended following Step 5 of this site. Me as usual, jumped into the deep end of the pool against the advice of a software specialist, another brother. Lazy me did a total copy and paste of the scripts but ended with an "abort" output. Then reading the first line of that section which requires one to copy and paste "one line at a time", things seem to work out fine. After the last line was entered, a restart is required. A recheck with the Software Updater gives a computer is up to date message. Yahoo!
