I think the bug submitter just broke his system, the log just started with the error message; and it was perfectly fine in the previous run, just look a few lines above and you see:
Setting up libsystemd0:amd64 (229-4ubuntu6) ... Setting up libsystemd0:i386 (229-4ubuntu6) ... Setting up systemd (229-4ubuntu6) ... So, without further input, I can't say anything about this. Furthermore, apt's history log only shows the command and what started it, but does not get any further. It would be a good idea to get the dpkg.log file, that contains the actual dpkg logs (status changes, etc). Then we can see when it broke, but it does not look like apt broke it. ** Changed in: apt (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1585710 Title: package libsystemd0:amd64 229-4ubuntu6 failed to install/upgrade: Paket libsystemd0:amd64 kann nicht konfiguriert werden, da libsystemd0:i386 nicht bereit ist (aktueller Status »half-installed«) Status in apt package in Ubuntu: Incomplete Bug description: Error occurred while apt upgrade ProblemType: Package DistroRelease: Ubuntu 16.04 Package: libsystemd0:amd64 229-4ubuntu6 ProcVersionSignature: Ubuntu 4.4.0-22.40-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 AptOrdering: libsystemd0: Configure libsystemd0: Configure NULL: ConfigurePending Architecture: amd64 Date: Wed May 25 18:33:53 2016 ErrorMessage: Paket libsystemd0:amd64 kann nicht konfiguriert werden, da libsystemd0:i386 nicht bereit ist (aktueller Status »half-installed«) InstallationDate: Installed on 2016-04-29 (26 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) RelatedPackageVersions: dpkg 1.18.4ubuntu1.1 apt 1.2.10ubuntu1 SourcePackage: systemd Title: package libsystemd0:amd64 229-4ubuntu6 failed to install/upgrade: Paket libsystemd0:amd64 kann nicht konfiguriert werden, da libsystemd0:i386 nicht bereit ist (aktueller Status »half-installed«) UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1585710/+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
