--- Comment #30 from Rosanne DiMesio dimesio@earthlink.net --- My understanding (Scott, correct me if I'm wrong) is that "flavor" vs. "derivative" is an official distinction made by Ubuntu. The instructions on our site should be consistent with Ubuntu policy, and the patch I submitted addresses that by changing "derivatives" to "flavors" in the page heading and first paragraph in addition to adding the warning I suggested in comment 27.
Since Mint is a derivative, not a flavor, the instructions on that page were never meant to apply to them. The error, as I see it, was in not making that clear, and that's what my patch aims to correct.
OTOH, a much simpler solution would be to eliminate the page altogether and have the link on the main Downloads page lead directly to https://launchpad.net/~ubuntu-wine/+archive/ubuntu/ppa. There's nothing on the Ubuntu download page that isn't documented elsewhere.
