You've not given much information, but chances are you're using UBports [1] and not Ubuntu [2]. UBports is built on top of an older version of Ubuntu, which is why you won't be able to upgrade to 20.
If you really need the absolute latest packages, consider one of the Arch distros. They don't tend to be as "user friendly" and you might find you're having to compile programs, etc, by hand. If you're not too up on your Linux, I would suggest sticking with UBports, it'll be the best out of the box experience for most users.
