"I tried burning an ISO to a DVD, and burning stopped at 99% with an error saying: "Fatal error during recording: Invalid argument" I was using the dvd+rw-tools 'growisofs' in Mint 19.1 "Tessa" MATE (64-bit). After giving up with finding a solution, I decided to see when the k3b page (k3b.org) was last updated. It was last modified on 6 January 2012. That's definitely outdated! If you're also having problems with k3b, try Brasero instead. It's more up-to-date, and I managed to successfully burn an ISO to a DVD."
