There's a checkbox somewhere in the update manager to disable the check for version upgrades. Normally the LTS releases won't prompt unless there is a newer LTS, but you can completely disable it.
Years ago when Free Geek was using Ubuntu we had to disable that function because people kept updating by accident. The difference between a regular security update and a full blown dist-upgrade isn't really that obvious in the GUI interface. A lot of people brought in systems that were in a half old, half new state. I expected them to improve the updater, but given how many times PLUG members mention apt-get issues it looks like nothing has changed since 12.04. There is also a feature to use a CDROM or USB installer as a package source. Since you mentioned you inserted a USB stick with 18.04 and then booted to 16.04, it might have asked if you wanted to use it for the update. If you aren't paying super close attention it is really easy to enable it and start a partial upgrade, thinking that it's just checking for the latest firefox security patch... Call it a UX bug... Typically you can easily avoid the problem simply by being aware that it wants to do it this way.
