update-manager crashed with ImportError in /usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeQuirks.py: No module named plugincore.manager

Status changed to 'Confirmed' because the bug affects multiple users.

Hello,

I am getting this same error. Has a solution been found?

Last night I updated to Precise Pangolin... or so I thought

[CODE]%lsb_release -rd
Description: Ubuntu quantal (development branch)
Release: 12.10[/CODE]

I must empatically state I did NOT do this purposefully. All I want is to get back to Gnome and get the functionality back that Unity took away. "Downgrading" to Precise Pangolin would be *great*.

When I attempt to get GNOME back from the Software Center I get

[CODE]"gnome: Depends: gnome-core (= 1:3.0+6ubuntu3) but 1:3.0+6ubuntu3 is to be installed"[/CODE]

So then I attempt to install "gnome-core" from Synaptic

[CODE]The following packages have unresolvable dependencies. Make sure that all required repositories are added and enabled in the preferences
gnome-core:
 Depends: evolution-data-server but it is not going to be installed
 Depends: gnome-contacts but it is not going to be installed
 Depends: gnome-panel but it is not going to be installed
 Depends: gnome-session but it is not going to be installed
 Depends: gnome-session-fallback but it is not going to be installed[/CODE]

So I attempt to use Synaptic to fix install evolution-data-server, but

evolution-data-server:
[CODE] Depends: evolution-data-server-common (=3.2.3-0ubuntu7) but 3.4.3-1 is to be installed[/CODE]

This is what other Ubuntu people have referred to as "Dependency Hell".

How can I get GNOME back?](*,)

Reproducible in Quantal with

$ update-manager --dist-upgrade

and indeed /usr/lib/python3/dist-packages/janitor is missing the plugincore subpackage. Probably a packaging bug. Investigating...

This bug was fixed in the package update-manager - 1:0.164

---------------
update-manager (1:0.164) quantal; urgency=low

  [ Brian Murray ]
  * DistUpgrade/DistUpgradeApport.py: ensure package install failures are
    tagged dist-upgrade

  [ Robert Roth ]
  * UpdateManager/UpdateManager.py: check for None type from
    get_last_update_minutes (LP: #1013325)

  [ Colin Watson ]
  * DistUpgrade/NvidiaDetector, debian/control: Update symlink to Python 3
    version, available as of ubuntu-drivers-common 1:0.2.55.
  * debian/rules: Make sure to run setup.py with the default python3 last,
    so that scripts get correct #! lines.

  [ Barry Warsaw ]
  * pre-build.sh:
    - Add python-gi as an explicit dependency.
    - python3-mock is required.
  * setup.py:
    - Fix the installation of the janitor.plugincore package for Python 3.
      (LP: #1013490)
    - Calculate the setup() version number from debian/changelog.
    - Remove package_dir since it's not actually needed.
    - Whitespace normalization.
  * tests/Makefile
    - Add sleep between Python 2 and Python 3 invocation of tests under
      xvfb-run, otherwise I get crashes where xvfb doesn't come up.

I don't really understand what you're referring to, but none of these sound
like they would indicate update-manager bugs.
