Did you mean to ask about the repositories being updated for Ubuntu 20.04? What are these conflicts that you are particularly experiencing on Insync 3?
I sometimes regret not blocking updates to Insync once there’s a version that’s seamlessly working because predictibly an update comes that breaks it all. I had some hesitation before this update and, alas, here I am with no sync. The work I’ve done on my other computer is currently unavailable to me. Didn’t notice until now, but all the files from the past few days are not updated. Very distressing. I really should be looking for another syncing solution.
