Because update-manager depends on python3-distupgrade and imports the size checking code from there. It does not make sense to have two copies of this implementation (with different bugs). > Doesn't update-manager need to check free space before installing > new kernels?

Yes, and this now uses the code in ubuntu-release-upgrader instead of having update-manager call into u-r-u's python module and u-r-u call back into update-manager.

Creating the file in /var/tmp means that it cannot atomically replace the existing initramfs; a mv from /var/tmp to /boot then becomes a non-atomic removal and replace, which means there is a window during which the initramfs on disk for the default kernel will be broken and a power event will cause the system to fail to reboot. That is not a trade-off we are ever going to make. The right fix for the out-of-space-on-removal problem is to fix the kernel packaging to not regenerate initramfs on removals of linux-image-extras or linux-image-signed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1646222 Title: calculation of needed free space in /boot is inaccurate and causes refusal to upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1646222/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
