Once the installation is complete, you can boot from the USB containing the installation, rather than booting from the live ISO. Lubuntu will install itself to your flash drive as if it were installing to any other drive in your system. Here’s a picture of the screen where you need to make the changes: Use the “Erase disk” installation option, and change “Swap to file” to “No swap” for the sake of flash drive longevity. When you get to the “Partitions” screen of the installation, click the dropdown next to “Select storage device”, and select your blank flash drive. Just boot up the live ISO, plug in a blank flash drive of a sufficient size, and then follow the Lubuntu installation process. However, if you’re booting from a live ISO for the sake of having an OS on a USB drive, you can install Lubuntu to a USB drive the same way you’d install it to a hard drive. A live ISO should be used for testing out the OS, offline maintenance, and installation. I’ve believe I’ve gotten hacked from failing to update my system regularly (yes, even on Linux). Even if Firefox is up to date, there’s lots of software on a live ISO, and there have been a lot of security updates between now and 6 months ago.
