I'm very frustrated. I spent 20+ years in IT (until 2002) and can't figure this out. I just received a Linux Lite 5.0 on as bootable live usb flash drive. I'd like to replace Windows 7 on an older laptop, It boots fine. Where do I go for detailed instructions as to what to do? I can't install either of the printers on my home network. LinuxLite can see them, but I don't know how to get the drivers installed. Also, I can't update the OS - here is what I get:
