I have a setup upgraded from 20.04 to 22.04 and now I'm trying to upgrade to 24.04.
The setup complains I needed 900mb EXTRA free on /boot. The partition is only 700mb, and it's true, it filled up lots of times over the years, since old kernels don't seem to be cleaned up automatically! Anyway I could free up 537mb and these are the steps I did to hack the system into upgrading nonetheless: * start do-release-upgrade * Ctrl-Z when the installer prints it's unpacking files. (you might have to try a few times but for me it worked on first try) * Find the file /tmp/ubuntu-release-upgrader-<random hash>/DistUpgradeCache.py (a random directory name will be used) and find the line where space_in_boot is assigned. Change it to space_in_boot = 1 and save. * the 'fg' shell command to resume the installer. It should not complain this time. I was able to upgrade perfectly fine this way. But make sure there aren't any kernel packages installed that will regenerate the initramfs during upgrade (just rm'ing the initramfs files in /boot can cause this). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1988299 Title: Can't upgrade from 20.04 to 22.04 due to extreme space requirement for /boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1988299/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
