Does my current version of Ubuntu already have an iso file. If so where do I find it to copy to a USB so I can upgrade

I want to upgrade to Ubuntu 18.04 (and then incrementally to later versions) but I can't find the iso file which I need to copy to a flash drive before I can download 18.04. Once found, how do I copy it?

Solution 1:

You don't need to copy any ISO file to upgrade to a newer version of Ubuntu. There are plenty of online tutorials on how you can perform an upgrade: https://ubuntu.com/tutorials/upgrading-ubuntu-desktop#1-before-you-start

If you want to do a clean install of the newest version of Ubuntu, then you'll need an ISO file on a USB drive, but you don't need to copy one from your current system - just download the newest version's ISO from Ubuntu's website.
