Comment 10 for bug 975320

This seems to be the catch-all bucket for errors of the type:
"""
TransactionFailed: Transaction failed: None
 The following packages have unmet dependencies:
"""

The most recent errors from errors.ubuntu.com looks like this:
"""
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/defer/__init__.py", line 473, in _inline_callbacks

A quick sample of a dozen or so show me: "language-pack-kde-en:". Also interessting is that its happening mostly on 12.04:
"""
1:0.156.14.11 (12.04)
1851 instances

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.
