[Bug 48627] Re: Poor resolution of "database locked" problem

[Christian Convey]

I get the same basic issue with "sudo aptitude update".  It was hanging
on one of the package repositories, so I had to ctrl-C it.   Subsequent
attempt to re-run the command gave me this error:

E: Could not get lock /var/lib/apt/lists/lock - open (11 Resource temporarily unavailable)
E: Couldn't lock list directory..are you root?

Cancelling a hanged aptitude/apt-get/adept operation should be
considered a first-class operation that leaves the system in a usable
state.
