Package: rabbitmq-server
Version: 2.6.1-1
Severity: serious
Hi,
I'm sorry that it's the 2nd time today that I have to send a RC bug
against this package... :(
This one is very easy to reproduce. Luckily, it's also very easy to fix!
Why are you even trying to userdel rabbitmq? Just don't do that, it's
really ok (and I believe *better*) to leave the system user when the
package is removed. Anyway, the issue is very simple: you are deleting
the user *before* rabbitmq had enough time to shutdown. That's in fact
one more reason why you should be using start-stop-daemon, in your init.d
script, which will wait nicely until the daemon dies.
Anyway, here's how to reproduce. Install a fresh SID, then do:
apt-get install rabbitmq-server
Then try to remove:
apt-get --purge remove rabbitmq-server
Then here's the error:
Reading package lists... Done

Reading state information... Done

Of course, if you do that a 2nd time, since the daemon is already stopped,
it will work.
Cheers,
