Recently, the nvidia-dkms driver updates wouldn’t build for 5.x series kernels, so if you hadn’t cleaned up old kernels, the update bombed out before updating the initrd filesystem, the system couldn’t boot without intervention. Thankfully, I noticed before trying to reboot my work desktop, and the solution was “apt autoremove && apt upgrade”.
But the install media for my desktop at home was 18.04, and it’s running 26.04 now. It has an AMD GPU, so it hasn’t had update problems.

If your playbooks don’t include an autoremove, you’re doing it wrong!
Or rather, lessons learned from when the default /boot partition was only like 100 MB.
