[Ubuntu LaunchPad bug #1335391](https://bugs.launchpad.net/ubuntu/+source/etckeeper/+bug/1335391) (Quoting the LaunchPad bug below, but I have experienced this issue in an identical manner.) I have configured etckeeper to use git. It works fine if I use apt-get or synaptic packet manager. But when the update-manger install new packet versions it ends with an "installation failed" message. When I check the status of the git repository in the etc directory, some changes are not commited, e.g.: On branch master Changes to be committed: (use "git reset HEAD ..." to unstage) modified: apt/apt.conf.d/01autoremove-kernels modified: init.d/resolvconf ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: etckeeper 1.9ubuntu2 ProcVersionSignature: Ubuntu 3.13.0-29.53-generic 3.13.11.2 Uname: Linux 3.13.0-29-generic x86_64 NonfreeKernelModules: wl tbs6982fe tbs6680fe tbs6923fe tbs6985se tbs6928se tbs6982se tbs6991fe tbs6618fe tbs6922fe tbs6928fe tbs6991se ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 CurrentDesktop: Unity Date: Sat Jun 28 09:42:13 2014 InstallationDate: Installed on 2014-03-30 (89 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Daily amd64 (20140329) PackageArchitecture: all SourcePackage: etckeeper UpgradeStatus: No upgrade log present (probably fresh install) mtime.conffile..etc.etckeeper.etckeeper.conf: 2014-03-30T16:33:03.109833
