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?

Why do you need an iso file for upgrading? Which version do you have now? Check [this](https://askubuntu.com/questions/91815/how-to-install-software-or-upgrade-from-an-old-unsupported-release).

If you want to upgrade to a current release you can do it without any iso file with the command `do-release-upgrade`, but must do it stepwise between LTS versions. If you want to install from an iso file, you should [get the iso file of the version and community flavour you want](https://releases.ubuntu.com/), for example 20.04.3 LTS (now the latest and greatest LTS point version).

The ISO file is used to install a system, not upgrade it.

please edit the version you are running now into your question.if you are running an intermediate version like 15.04/10 or 17.04/10 it might be advisable to do a clean install of a LTS from an ISO.

In an Ubuntu tutorial it tells me that with a bootable USB stick I can either upgrade or install a new version of Ubuntu.

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.

an iso file burned to a DVD works just as well

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
