> For them, dist-upgrades are well understood and not blind luck. Ubuntu specifically tells you not to do a dist-upgrade, so your supposed evidence of how easy it must be doesn't even pass the smell test. The "correct" upgrade process is do-release-upgrade. Unfortunately, that process still is not a complete solution, as demonstrated by the multiple clusterfucks I've had to clean up when people tried to use their upgrade process. Even if they had succeeded, that would tell you nothing -- Ubuntu is a commercial operation with a substantial amount of money behind it. Linux Mint is not. ReactOS would be a perfect Windows clone if everything a funded corporation accomplished were easy.
