Newbie here. About 3 weeks ago I switched from Windows 10 to Ubuntu 21.04. Occasionally I do sudo apt update and sudo apt upgrade. Does this update/upgrade all my apps? If not, how can I tell which apps are not getting updated/upgraded?
I want to keep all my apps up to date. I have installed a few snaps, flatpaks and appimages.

Apt only works on deb packages. Nothing else.
It doesn't work on Snaps. Nor Flatpaks. Nor Pips. Nor Wheels. Nor Brews. Nor git clones. Nor source code that you compiled or downloaded or write. Nor anything else.
There is NO application that handles "everything."
As the system admin, it's YOUR responsibility to keep track of what you install. Apt is one great tool to help make your tracking super-easy and prevent many common mistakes, but it's just software: It cannot be responsible for the consequences of your decisions.
Generally, for new users, we recommend that you stick to the default Deb and Snap packages in your Ubuntu Software application. When you are ready to handle the learning curve, risks, and bookkeeping of the many other methods, then you can swim in the deep water.
