I updated to 1.7.1 - but got some nagging about Python 2, so decided to bite the bullet and update my OctoPi from an older one (15 i think) to 18. Did a full backup first of course. When booting into 18 - i tried to restore my backup from within the Wizard - but was unable to because it seems Octopi has 1.5.x installed. Makes sense. I had to go through the motions of the whole wizard, and then, update Octopi, and then restore my backup. Not the end of the world - but it would have been oh so much more elegant if the Setup Wizard would have allowed me to update to the latest version there and then when it noticed my backup was taken on newer version than the installed
Just a thought!
