🐧 update-initramfs is stuck

I was running into an issue on my Ubuntu 22.04 server where the kernel was stuck on 5.15; I never thought much about it as things were working fine, and the system was pretty locked down.

However, once I started thinking about it a long while back (Many upgrades ago), I remember freezing kernel updates due to some video card issues that I was having with docker and passthrough to a Plex container.

By this point, things SHOULD work fine with a newer kernel and all the updates again. I don't even remember when I froze the kernel, but ample time had passed, and I was giving the community the benefit of the doubt that things were fixed by now. Running the following commands kicked everything into gear.

sudo apt remove initramfs-tools
sudo apt install initramfs-tools

After running those commands, I completed the update to the server with the shiny new 6.5 kernel after a reboot.

I am mainly writing this here for future reference for myself but hope others fine it helpful if stuck wondering why things are not updating as expected.…
