We generally don't know how much space is going to be needed. APT only
keeps 2 kernel versions around, and the /boot partition is sized
accordingly for 3.
If you override this by marking kernels as manually installed, or
manually installing other versions you need to ensure that there is
enough space for those.
I only see two kernels installed though, so it's not clear to me how you
could be running out of space in /boot in the first place.
Are there additional files in there? The kernels shouldn't fill that up.

Bug description:
System information:
ubuntu 23.04 x86_64
6.2.0-24-generic
Upgrading the system:
$ sudo dpkg --configure -a
Setting up linux-firmware (20230323.gitbcdcfbcf-0ubuntu1.2) ...
update-initramfs: Generating /boot/initrd.img-6.2.0-24-generic
I: The initramfs will attempt to resume from /dev/dm-2
I: (/dev/mapper/ubuntu--vg-swap_1)
I: Set the RESUME variable to override this.
zstd: error 70 : Write error : cannot write block : No space left on device

Check space left (none):
$ df -h /boot

What is required is to remove older kernels (and purge them most likely).
List all the installed kernels except the current one:
$ dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed
"s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d'
linux-headers-6.2.0-23
linux-headers-6.2.0-23-generic
linux-headers-6.2.0-25
linux-headers-6.2.0-25-generic
linux-image-6.2.0-23-generic
linux-libc-dev:amd64
linux-libc-dev:i386
linux-modules-6.2.0-23-generic
linux-modules-6.2.0-25-generic
linux-modules-extra-6.2.0-23-generic
linux-modules-extra-6.2.0-25-generic
Is not possible to uninstall any kernel because fails:
$ sudo apt purge linux-headers-6.2.0-23
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to
correct the problem.
Reconfigure fails again so some kernel have to be manually removed to free up
space:
$ sudo rm /boot/initrd.img-6.2.0-23-generic
$ sudo rm -rf /boot/initrd.img-6.2.0-25-generic.new
Now you can reconfigure:
$
Remove kernels:
$ sudo apt purge linux-headers-6.2.0-23 linux-headers-6.2.0-23-generic
linux-headers-6.2.0-25 linux-headers-6.2.0-25-generic
linux-image-6.2.0-23-generic linux-modules-6.2.0-23-generic
linux-modules-6.2.0-25-generic linux-modules-extra-6.2.0-23-generic
linux-modules-extra-6.2.0-25-generic
Reboot:
$ sudo reboot
Upgrade as usual:
$ sudo apt update && sudo apt upgrade
Before upgrading new kernels I need to check for free space and remove
older kernels manually. Fix this so there's only one kernel left.
