Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
touch: cannot touch '/boot/initrd.img-4.4.0-31-generic.new': Read-only file system So your /boot partition mounted from /dev/sda1 was read-only. CurrentDmesg.txt shows: [ 81.268414] sd 1:0:0:0: [sda] 124735488 512-byte logical blocks: (63.9 GB/59.5 GiB) [ 81.287023] sda: sda1 sda2 sda3 [ 82.689255] EXT4-fs (sda2): mounting ext2 file system using the ext4 subsystem [ 82.708006] EXT4-fs (sda2): warning: mounting unchecked fs, running e2fsck is recommended [ 82.727344] EXT4-fs (sda2): mounted filesystem without journal. Opts: (null) [ 82.734136] FAT-fs (sda1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck. So running fsck and mounting /boot read-write should solve the issue. Feel free to continue to report any other bugs you may find. ** Changed in: initramfs-tools (Ubuntu) Status: Confirmed => Invalid -- 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/1603286 Title: package linux-image-extra-4.4.0-31-generic 4.4.0-31.50 failed to install/upgrade: run-parts: /etc/kernel/postinst.d/initramfs-tools exited with return code 1 Status in initramfs-tools package in Ubuntu: Invalid Bug description: Install attempted by Ubuntu Mate included Update Manager along with Grub2 update.
