Raspiberry Pi 3 sudo apt-get dist-upgrade

Is it a good idea to run sudo apt-get dist-upgrade on the currently released image for Navio2? I am just starting and I was wondering if an upgrade was required/recommended before actually running APM.

Upgrades do sometimes break things.
We put some effort to make it as safe as it can possibly be, though. Either way, this is how ArduPilot package gets upgrades. So you are going to run this command eventually.
