[Bug 1216649] [NEW] software updates won't run

[bdubawoop]

Public bug reported:

installed 12.04lts a few weeks ago.

today, when i booted up the desktop software updater in upper right corner said it was up to date but because I hadn't
booted in a couple weeks I ran it anyway.

it said 'not all updates can be installed' & offered a partial update or
close.

when I told it to do partial update it errored out saying apt-get or
aptitude was running, which it wasn't.

I then did apt-get update from a terminal. it d/l a bunch & then exited normally. when i looked at the desktop updater
it now said updates ready.

It installed about 100 & exited normally.

I got a ton of hits on this with google but its not clear what the cause
is.

it appears that running 'apt-get update' fixes the problem but what is
the problem in the 1st place?
