Public bug reported:


the available space on /boot must be checked before a new kernel is

Background: update procedure is very stable on Ubuntu, except Kernel upgrades. Some years ago Ubuntu created the standard /boot & efi system partition with 512Mb each (and I cannot resize the partition easily due to encryption). 
This is not sufficient for 4 parallel installed kernels. If there is not enough space, Discover simply outputs a message like "Firmware was not installed, press OK". Then Discover completes the upgrade process of all other components successfully.

On the next reboot, the user is surprised with a Kernel panic error.

Again, there seems to be much effort to make the upgrade procedure
stable and it is, but every few months the complete system break due to
the kernel upgrades and can only be rescued by chrooting into it.

BTW: I know about "Unattended-Upgrade::Remove-Unused-Kernel-Packages",
but I doubt that the majority of users uses it.
