rc linux-image-5.11.0-25-generic 5.11.0-25.27~20.04.1 amd64 Signed kernel image generic

I am trying to delete old kernels. The highest number is the most recent kernel but I don't know what the version number is. Where is it is along that string of characters?

I ran uname -r and got:

5.11.0-41-generic #45~20.04.1-Ubuntu SMP Wed Nov 10 10:20:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

So I'm pretty sure that it is the most recent, but I would like to know what I'm looking at.

You're running kernel version 5.11.0-25-generic:

The current version for stock 20.04 – as of this answer – is 5.11.0-40-generic. You may want to update your OS in the near future to ensure you have the latest security updates at the very least 👍🏻

If you are trying to remove old kernels, there is an easier method ...

sudo apt autoremove --purge

or

sudo apt autopurge

In addition to old kernels, it will also remove any packages that may have been installed but are no longer needed.
