In main.log we see the following:

2012-09-20 15:17:22,048 DEBUG failed to SystemUnLock() (E:Not locked)
2012-09-20 15:17:28,673 ERROR Cache can not be locked (E:Could not get lock //var/lib/dpkg/lock - open (11: Resource temporarily unavailable), E:Unable to lock the administration directory (//var/lib/dpkg/), is another process using it?)

Perhaps the software updater was still doing something?
