I’m trying to use balena for the first time, practicing on Iso files that I know are good, and have flashed using rufus. The error I’m getting is the same for all the iso’s I’ve tried: “Something went wrong, if it is a compressed image please check that the image is not corrupted. No polkit identification agent found.” I’m running version 1.5.109 on ubuntu 12.04.
Could somebody please advise? Thanks, Leo
