Right so it seems we forgot to bump the size requirements in ubuntu- release-upgrader when bumping them in the installer in bug 1959971, you probably should not have been able to upgrade. Albeit the size it seems is determined from the initramfs that is in /boot.
We also don't seem to acccount for system.map which is about 10MB per kernel Unfortunately there isn't much else we can do here. You can of course opt to 1) set MODULES=dep in /etc/initramfs-tools/initramfs.conf - this will mean that you can't replace your mainboard or swap your disk into a different machine as the initrd will only include modules relevant to the device the system is running on 2) specify COMPRESS=xz or preferably if available a higher COMPRESSLEVEL=1 in the same file such that compression is higher. I don't know why your initramfs are that big, presumably you are using nvidia gpus? With 3 kernels on my /boot and no out-of-kernel drivers I use 438MB. ** Tags added: rls-ll-incoming -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/2027847 Title: Bump minimum /boot size in ubuntu-release-upgrader Status in apt package in Ubuntu: Won't Fix Status in dpkg package in Ubuntu: Invalid Status in kernel-package package in Ubuntu: Invalid Status in linux package in Ubuntu: Invalid Status in linux-firmware package in Ubuntu: Invalid Status in linux-kernel-headers package in Ubuntu: Invalid Status in linux-restricted-modules package in Ubuntu: Invalid Status in ubuntu-release-upgrader package in Ubuntu: New 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 E: mkinitramfs failure zstd -q -1 -T0 70 Check space left (none): $ df -h /boot Filesystem Size Used Avail Use% Mounted on /dev/sdb2 707M 693M 0 100% /boot What is required is to remove older kernels (and purge them most likely).
