My understanding was that this was not primarily about the hack on Feb 20 where some folks got an iso with the backdoor. The main thing to me is about the lack of security notifications and also updates on kernels. I don't mind old software as long as the security updates are put through. I do see a lot of notices for updates in Mint, almost every day. Just a day or 2 ago I got an update for a program that broke it. This morning the update was there to put it right. Someone is on the ball there, so I'm wondering if this lack of security updates is a real issue other than the kernels.
I did install the new Ubuntu and cinnamon works great on it. I'm still deciding on whether to go through the trouble of getting all my nice settings etc set up on a new system. I may just wait until I get a new computer. I'm thankful for the heads up here, though.
