Going from 20.04.2 to 20.04.5?

[impy101]

I am currently on 20.04.2 and I want to go to version 20.04.5 but when I do apt update and apt upgrade it's not doing anything.

Is there a guide on how I can go to 20.04.5?

Welcome to the Ubuntu forums. If you have Ubuntu 20.04.2 installed, the command to to update your system is:
sudo apt update && sudo apt upgrade
You will be asked for your password.
To update your computer you must be (at least for a short period of time) a super user.

Try sudo apt full-upgrade

From the manpage:

       full-upgrade (apt-get(8))
           full-upgrade performs the function of upgrade but will remove currently
           installed packages if this is needed to upgrade the system as a whole.

Don't worry, this will NOT take the system to a different release.

But, it will take you to 20.04.6, which is the current version of the 20.04.x line.

$ lsb_release -d
Description:    Ubuntu 20.04.6 LTS

20.04.5 is unsupported at this point. Ubuntu only supports the original 20.04.{nothing} kernel and the latest "dot release" 20.04.6 kernel. Support for the middle-HWE kernels (20.04.1, .2 .3 .4 .5) was dropped a few years ago. It had ramifications Canonical learned were just too hard to keep maintaining.

If the full-upgrade doesn't get to .6, then install the HWE kernel package following these instructions: https://wiki.ubuntu.com/Kernel/LTSEnablementStack

I did that as root, but I'm still on 20.04.2

Are you sure it doesn't say you are on 22.04.2?
The version you have installed is for 22.04.2.

20.04.6 returns this:

$ apt policy base-files
base-files:
  Installed: 11ubuntu5.7
  Candidate: 11ubuntu5.7

Details matter. Run lsb_release -d to see what APT thinks you have installed.
