[Bug 1267564] [NEW] etckeeper with git breaks package upgrades that touch /etc

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Robie Basak (racb):

I tried to upgrade Ubuntu 12.04 Precise system to 14.04 Trusty (alpha)
with "do-release-upgrade -d". I had etckeeper installed and configured
to use Git. The upgrade failed at the very end, because etckeepers DPkg
::Post-Invoke hook failed. The reason was  that git user.name and
user.email were not configured, but this was not an issue before the
upgrade (i.e. apt/dpkg worked just fine).

It would be nice, if this kind of configuration issue was detected
before the upgrade.

<pre>
Running mktexlsr. This may take some time... done.
Processing triggers for bamfdaemon ...
Rebuilding /usr/share/applications/bamf-2.index...

*** Please tell me who you are.

Run

  git config --global user.email "you at example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: unable to auto-detect email address (got 'root at untamo.(none)')
Error in function:

A fatal error occurred

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade has aborted.
Your original sources.list was saved in
/etc/apt/sources.list.distUpgrade.

SystemError: E:Problem executing scripts DPkg::Post-Invoke 'if [ -x
/usr/bin/etckeeper ]; then etckeeper post-install; fi', E:Sub-process
returned an error code

No pending crash reports. Try --help for more information.

Could not install the upgrades

The upgrade has aborted. Your system could be in an unusable state. A
recovery will run now (dpkg --configure -a).

Upgrade complete

The upgrade has completed but there were errors during the upgrade
process.
