Look at:

man apt-key

When you upgrade you will still have access to the kernel your running now to fall back on.

That's what I'm using on two different computers and everything is running fine here.

I typed the suggested man apt-key. I got lost what to do? You going to have to explain a bit more I'm lost. Sorry, somewhat a newbie Still learning this linux thing.

There are 'sources' you can get software from. The parent company of ubuntu is Canonical, they provide many programs and updates. Sometimes, users will build software or update it before it becomes 'mainstream', these are often called beta-packages. These packages are not 100% ready for public use, but usually work for the majority of users (there is always exceptions). Programmers often put their work on the internet for people to test, this is usually done via a 'PPA' (personal package archive)

You will need to install a password 'key' for each PPA you add to your /etc/apt/sources.list

The key should be found on the same web-page the 'source' file was downloaded from.

CShaum, can you run sudo apt-get update and post the output here?

That's what I did last night. Did the get-apt update command to see what would happen. And sure enough it detected the very one that it was warning about. I launch off and updated and so far so it has been good. Apparently they can be trusted. Computer even booted a touch faster. :-)
