it's a _lock_, not a broken install (though there could be a broken install, 
too).  The lock file should be in /var/cache/apt somewhere, iirc.  It's just 
called "lock".  Just remove it.

If you can't find it there (of course I don't have one), check in /var/run 
or as a last resort run "updatedb" and then "locate lock"
