update-manager crashed with Depends in _run_in_dialog(): libx264-120 but it is not installed

[Eelbuntu]

I think it has something to do with trying to install flash plugins from firefox

It looks like the crash is aptdaemon.

[Launchpad Janitor (janitor)]

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

[Michael Vogt (mvo)]

I have no strong opinion if aptdaemon should raise a exception or just set the transaction error state, I slightly prefer the later though.

I installing upgrade for frostwire data

[Torgny (torgny-bjers)]

I encountered this when I had force-installed a package with unmet dependencies (system76-driver) on a clean 12.04 LTS that does not have the old gnome2 packages that would remain after a distribution upgrade. The system refused to install the driver's requirements because they would conflict and that's when the crash occurred.

In 12.10 todays update has removed i386 packages. While trying to reinstall crossover which depends on some i386 stuff. The package list got broken and system fails to update any further, need help.

This is the most common problem on errors.ubuntu.com as of December 5, 2012:

Today this bug is the most frequent recorded error for Ubuntu users overall (via its private duplicate bug 979278). Philip Alring Rützou Aakast is not subscribed to this bug report and has never reported or fixed any bugs, so I believe he marked this as fixed by mistake.

This seems to be the catch-all bucket for errors of the type:
"""

 The following packages have unmet dependencies:

The most recent errors from errors.ubuntu.com looks like this:

A quick sample of a dozen or so show me: "language-pack-kde-en:". Also interessting is that its happening mostly on 12.04:
"""

Now that is puzzling as https://launchpad.net/ubuntu/+source/language-pack-kde-en-base shows that version 1:12.04+20120801 is there and that hasn't changed in a long time.

[Michael Vogt (mvo)]

A common theme I see in a lot of the recent reports is: " /home/oem ", LANGUAGE=en_IN:en and the version reference to 4:4.8.3-0ubuntu0.1 is a version in precise-updates that is no longer in the archive. But there are also counter examples, so this might be a red herring.

But that also has not changed in a while, according to https://launchpad.net/ubuntu/+source/qt4-x11 it got updated in 2012-11-08

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
