I have a machine at home running Linux Mint 16 (Petra) that I decided to do an upgrade to 17 (Qiana), and what is it about Ubuntu and its derivatives that make doing an upgrade so difficult?! I've had Ubuntu itself break during upgrades before, and decided to quit using Ubuntu partially as a result. But I've had pretty good luck with Mint in the past, and, well, not so much any more. The networking is completely broken now. Not just wireless, but wired as well. ifconfig shows no network adapters other than loopback.
To be fair, I haven't had much of a chance to investigate to see if it's something incredibly simple, but if stuff like this keeps happening, I'm going back to a monolithic kernel and building everything from source ;)
