[Bug 1302380] Re: package installation failure during partial upgrade reports crash against ubuntu-release-upgrader

[Brian Murray]

As far as I can tell this is because do-partial-upgrade calls
doPartialUpgrade() from DistUpgradeController.py which doesn't use any
of DistUpgradeMain.py - particularly setup_logging.

Title:
  package installation failure during partial upgrade reports crash
  against ubuntu-release-upgrader

Status in “ubuntu-release-upgrader” package in Ubuntu:
  Confirmed

Bug description:
  I did a partial upgrade (update-manager -d) with a broken package
  (isc-dhcp-client) and it triggered this crash report.

  As a consequence:
  1. Package installation failures are reported against the wrong package
  2. errors on error.u.c are grouped in the same bucket, without any information about the origin of the failure making them useless
  e.g https://errors.ubuntu.com/problem/46463809739f8320957064ebeaa7f9abc1bd8fa4
  the traceback is simply: 
  SystemError: E:Sub-process /usr/bin/dpkg returned an error code (1), E:Sub-process /usr/bin/dpkg returned an error code (1)

  The expected behaviour is to generate a crash report directly for the
  right package.
