There are only two kernels on the system: 1. 5.4.0-72.80 2. 5.8.0-51.57~20.04.1
And after the kernel installation everything is fine, there is no problem to boot the 5.8.0-51.57~20.04.1.

Taking backup of boot.scr. Installing new boot.scr. However install the udev package that triggers update-initramfs and it will cause this failure immediately. Looks like it's the initrd.img-5.8.0-51-generic.new that's growing. Maybe the solution is to create a larger /boot partition as you mentioned. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926440 Title: udev in proposed does not work with 5.8.0-51.57~20.04.1 on Moonshot ARM64 (/boot filled up) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1926440/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
