Do we know any ETA when this advisory will be lifted? Does this only apply to fresh installs, or are upgrades equally affected? I know I can click through to Launchpad tickets, but I was rather hoping for some clearer statement somewhere (the primary Launchpad ticket has over 400 comments to sift through).

I only recently moved to Ubuntu Desktop, coming from Windows (though having used a lot of Linux on servers). I'm on 16.04 now, but I'd like to upgrade. I happen to be using a Lenovo YOGA 710-15IKB laptop.
