Protip, if you have access to the computer: `lsb_release -a` should list both release and codename. This command is not specific to Ubuntu.

Finding the latest release and codename is indeed a research task. I use Wikipedia[1] for that, but I feel like this should be more readily available from the system itself. Perhaps it is, and I just don't know how?

I typically prefer

  cat /etc/os-release

which seems to be a little more portable / likely to work out of the box on many distros.

		That's only if the distro is recent enough; sooner or later, you'll encounter a box running a distro version from before /etc/os-release became the standard, and you'll have to look for the older distro-specific files like /etc/debian_version.
