Your dpkg terminal log has a number of issues in it which may be unrelated to the install of python- six, but does show missing packages. I am marking this incomplete for now until we have a way of reproducing. ** Changed in: six (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to six in Ubuntu. https://bugs.launchpad.net/bugs/1493046 Title: package python-six 1.5.2-1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 127 Status in six package in Ubuntu: Incomplete Bug description: package python-six 1.5.2-1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 127 ProblemType: Package DistroRelease: Ubuntu 14.04 Package: python-six 1.5.2-1 ProcVersionSignature: Ubuntu 3.13.0-43.72-generic 3.13.11.11 Uname: Linux 3.13.0-43-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.6 Architecture: amd64 Date: Mon Sep 7 12:34:33 2015 DuplicateSignature: package:python-six:1.5.2-1:subprocess new pre-removal script returned error exit status 127 ErrorMessage: subprocess new pre-removal script returned error exit status 127 InstallationDate: Installed on 2014-12-18 (263 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) PackageArchitecture: all SourcePackage: six Title: package python-six 1.5.2-1 failed to install/upgrade: subprocess new pre-removal script returned error exit status 127 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/six/+bug/1493046/+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
