Why Won't PopOS Linux Update?

Episode 1657 (1:00:55)

Timmy from Oak Hills, CA
POP-OS

Timmy installed POP-OS Linux on an old HP laptop. But when he reboots, it won't update the system files. Leo says that this is a common issue in Linux, where, for security reasons, unsigned software isn't allowed to be installed into Linux. Leo says he will need to get the new key for that version of Linux and install it through the command line. Once that's installed, it'll update. Talk to System76.com support and they'll walk through it. What about the KeyRing password? Leo says it's probably login credentials.
