Some days ago I downloaded the fine new Linux Mint 18.2 (sorry not to remember it's name). I installed it with Cinnamon and updated and did some surfing in the Net. Meanwhile I used my second computer with Fedora 27 Beta
Now I am back on this PC. And some security updates should be installed. Although I have rules to remember my passwords, this time I can not generate the right one from my memory
I'm already 83 so my lovely daughter solaces me:
Do not panic dad. It's only demens senilis[/i.]
No other possibility than to install Mint again
