How do I go about fixing it from the git repository?

Hi,

You don't need to. It's a missing Pre-Depends on procps. Just install
procps and run "dpkg --configure --pending" afterwards (as root).

The according git commit is:

It didn't quite work Axel

Does this make it a different bug?

Thanks,

Hrm. Doesn't look as expected.

Maybe.

Thanks for the details. Will check next week when I've got access to a
quantal box.

Status changed to 'Confirmed' because the bug affects multiple users.

[udifuchs (udifuchs)]

For me, the post install script failed at the line: 'pkill -u hobbit vmstat'.

A work around it to run 'sudo -u hobbit vmstat 1'. This gives pkill something to kill. Then you can run in parallel 'sudo dpkg --configure --pending' to finish the install.

A more permanent fix would be to change the line in the script to 'pkill -u hobbit vmstat || true'.

udifuchs: Thanks for that hint. So it is indeed a different issue. Changing the title accordingly.
