Public bug reported: The seems to be an error in the intel_microcode hook for initramfs update. This breaks the initrd:
# file /boot/initrd.img-3.19.0-18-generic /boot/initrd.img-3.19.0-18-generic: ASCII cpio archive (SVR4 with no CRC) This is not the expected gzip file. I am not sure now, whether my system is bootable. Edit /usr/share/initramfs-tools/hooks/intel_microcode. Put an "exit" right after the comment header. This will disable the hook and generate a gzipped cpio archive. Xubuntu 15.04 initramfs-tools 0.103ubuntu15 I also checked an AMD-maschine. No Problems with the initrd. ** Affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New -- 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/1462788 Title: Initrd is not gzip archive Status in initramfs-tools package in Ubuntu: New Bug description: The seems to be an error in the intel_microcode hook for initramfs update.
