sudo apt update/sudo apt upgrade
It is actually very easy to break your install by doing this if you have made a habit of installing random .deb files from around the internet
APT can’t update things that are not in the repository and .deb files typically only work for a specific version of the OS (which is to say, they will probably work when you install them but break when you update).
You should in general never install a .deb file directly. Sometimes it might be necessary in order to install a program that the developer doesn’t support, but that lack of support should be a flashing warning light that the package will probably break something in the future.
There are ways to purge your system of orphaned .deb installs, and I suggest doing that before large upgrades

I have zero clue how to do that. I don’t even know what file extention they would be, or where I would get them, or what step 1 would be to installing them.

They would also be
.debfiles. If you wanted to install packageA.debthat depended onB.debandC.deb, withC.debitself depending onD.debandE.deb, you would work down the dependency tree to figure that out, obtaining the.debfile for each package as you went, then rundpkg install E.deb,dpkg install D.deb,dpkg install C.deb,dpkg install B.deb, and finallydpkg install A.debin that order.This is what
aptis designed to do for you, automatically.
