I'm using Ubuntu along side windows in dual boot. I downloaded, compiled and booted linux-stable kernel from Linux's official repository. Now I want to remove this kernel, I tried searching online.
But when i use dpkg --list | grep linux-image, I couldn't find linux-stable kernel which i downloaded, So I couldn't follow online guide.
srivathsa@srivathsa:~$ dpkg --list | grep linux-image
ii linux-image-5.11.0-25-generic 5.11.0-25.27~20.04.1 amd64 Signed kernel image generic

ii linux-image-generic-hwe-20.04 5.11.0.25.27~20.04.10 amd64 Generic Linux kernel image
where as kernel which i downloaded was 5.12.17.
So, how should I remove this kernel?
