oh neat! I have never upgraded Debian and now I get to learn how to.
lmk when you figure it out, I've been running apt full-upgarde non-stop for the past few days and it keeps telling me I'm on the most recent release - bs.
This is strange. You may have already solved your problem, but have you checked your apt sources list that it points to the right source (stable / oldstable) or (bookworm/trixie)?
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.
