Please have a look at the file uploaded with the bug... Df.txt... your boot partition needs to be cleaned up a bit.
I ran into this issue as well. I found that I was lacking /boot space. With a smaller /boot partition regular maintenance of the kernel packages must be performed. I myself had 6 different kernel packages and their baggage within /boot. I used Synaptic to remove the kernel images I no longer needed and at the shell level ensured that update-grub ran successfully. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1435420 Title: package linux-image-extra-3.16.0-33-generic 3.16.0-33.44 failed to install/upgrade: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 1 Status in initramfs-tools package in Ubuntu: New Bug description: i don t know ProblemType: Package DistroRelease: Ubuntu 14.10 Package: linux-image-extra-3.16.0-33-generic 3.16.0-33.44 ProcVersionSignature: Ubuntu 3.16.0-33.44-generic 3.16.7-ckt7 Uname: Linux 3.16.0-33-generic x86_64 ApportVersion: 2.14.7-0ubuntu8.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mizael 2574 F.... pulseaudio Date: Sun Mar 22 12:04:32 2015 DuplicateSignature: package:linux-image-extra-3.16.0-33-generic:3.16.0-33.44:run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 1 ErrorMessage: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 1 InstallationDate: Installed on 2015-01-08 (73 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) MachineType: POSITIVO POSITIVO MOBILE ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.16.0-33-generic root=/dev/mapper/ubuntu--vg-root ro quiet splash vt.handoff=7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
