I am attempting to show you how to ask smarter questions and avoid
making the mistakes that you have made so far.

If you interpret this as an attack, that is up to you, but it will be
very difficult to learn anything from anyone if you see it as an
attack when someone corrects you.

``sudo apt update''

This will update all your installed packages to the newest versions.
It will not install new packages, or remove anything.

This is AIUI and TTBOMK. I welcome correction.

It is still there.

However, if you want a full system upgrade, e.g. to the latest kernel,
which is very important for security and for fault-fixing, then
sometimes, it will need to install _new_ packages and that will
sometimes unavoidably mean _removing_ the old versions.

That is what

``sudo apt full-upgrade'' does.

These are basically the new shorter, more comprehensible equivalents to the old

``sudo apt-get upgrade''

and

``sudo apt-get dist-upgrade''

commands.

But if you prefer, you can still use the old commands. They still work fine.
