  1. After using dos and windows I started using Linux mint about a week ago, and I really like it. My problem is that every time I log off or restart I lose all my settings.,my display settings, passwords for network, firefox, thunderbird, etc. Be kind to me I am an 81-year newbie.

    Thanks

      I think you are using Linux Mint live session, better install Linux Mint to keep your settings persist after a reboot.

      Just update the repository cache and try again.

      $ sudo apt update
      $ sudo apt-get install stacer
      Or
      $ sudo apt install stacer

      • I had done that before attempting the install, but just to be sure, I tried it again and got the same result. It may be because the repository lacks a public key and is unsigned.
