I got the same error on my system when running apt-get install --reinstall initramfs-tools
By running apt-get install initramfs-tools it complained of not being able to create a file called /var/tmp/mkinitramfs-FW_XXXXXX This was because the folder /var/tmp didn't exist... I recreated that and both commands above worked fine again -- 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/1388353 Title: package initramfs-tools 0.103ubuntu4.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in initramfs-tools package in Ubuntu: Invalid Bug description: I just was updating package's package initramfs-tools 0.103ubuntu4.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 ProblemType: Package DistroRelease: Ubuntu 14.04 Package: initramfs-tools 0.103ubuntu4.2 ProcVersionSignature: Ubuntu 3.13.0-37.64-generic 3.13.11.7 Uname: Linux 3.13.0-37-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.6 Architecture: amd64 Date: Sat Nov 1 13:19:01 2014 DuplicateSignature: package:initramfs-tools:0.103ubuntu4.2:subprocess installed post-installation script returned error exit status 1 ErrorMessage: subprocess installed post-installation script returned error exit status 1 InstallationDate: Installed on 2014-07-17 (106 days ago) InstallationMedia: Ubuntu-GNOME 14.04 LTS "Trusty Tahr" - Release amd64 (20140715) PackageArchitecture: all SourcePackage: initramfs-tools SystemImageInfo: current build number: 0 device name: channel: daily last update: Unknown Title: package initramfs-tools 0.103ubuntu4.2 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1388353/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
