[bitbake-devel] bitbake hang due to dpkg error

I'm not sure if this was the right place to report a bitbake bug (or
at least what I believe is a bitbake bug).

Ubuntu 13.04 here. The issue I had was that something had interrupted
dpkg, this left around some kind of a lock. I ran a bitbake command,
in this case:

MACHINE=beagleboard ./oebb.sh bitbake console-image

And it hung, almost no cpu usage on the system.

I ended up aborting the tasks and at some point tried to do a dpkg
command like 'sudo dpkg --remove blah' and got:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure
-a' to correct the problem.

After running 'sudo dpkg --configure -a' I re-ran the bitbake command
and everything seems happy. It appears that bitbake was issuing an apt
or dpkg command and hitting the same issue I saw with the 'dpkg was
interrupted' error but it isn't handling that appropriately and was

What I'm not sure of is exactly where the hang was, I don't yet
understand bitbake. Here are the tasks that appeared to have been
locked up:

I can provide more information if it would be helpful, and if this
isn't the correct place just let me know and I'd appreciate if you
could point me in the right direction.
