There is a new application ready in our repo called "System Upgrade" (sparky-aptus-upgrade).
It provides the recommended way for upgrading Sparky without answers for some questions.
There is only one question you have to answer: Upgrade now?
The app has the internet test check out built in - if you forget to make connection, it will display specific info.
Sparky APTus lets you make every step in your way - it's manual tool, but sparky-aptus-upgrade can do it automatically, similar like in others distributions.
But it's smaller and faster, with 'sparky touch'.
Test it and install. please, and report anything wrong you find.
I was testing and rebuilding it last few days, so it should working fine.
If everything will be OK, I'm gonna enclose it to the next sparky iso images.
sudo apt-get update
sudo apt-get install sparky-aptus-upgrade
Run it from Menu-> System-> System Upgrade
