Package: apt
Version: 0.5.14
Severity: normal


EVENT DESCRIPTION

This bug cannot be easily reproduced, but this is what happened:

-  apt-get install mysql-server (I was upgrading)
-  ... apt-get hung

Hm, next I tried apt-get remove mysql-server, which could'n do it
either. The error message was something line "package is in very bad /
inconsistent state, you should install it first before removing". The
exact wording has passed, because my terminal did not have a big
scroll buffer where I worked at the time.

Next I tried apt-get --reinstall mysql-server but that hung
mysteriously too.

The error was simple: apt-get hung because it couldn't stop
mysqld_safe daemon. I had to kill it with -9 and continue
install as usual.

SUGGESTION FOR IMPROVEMENT

Suggestion one. Please include two step message, whenever a server is
going to be shut down:

	Stopping process (name) ...		<before>
	Stopping process (name) ...done.	<after>

If the installation process hungs, at least user can see where the
problem is. Right now there is only one message "Stopping ....", which
is printed too late - after success. 

Second suggestion. If it is possible, include a timeout, say 7 seconds
(this could be configurable), to let the kill command to run. If 
the process is still there, a message could be displayed:

	The process XXXX couldn't be killed with /etc/init.d/... stop
	I'm going to try killing it with -9

If this fails, the program could hand the situation to user to solve.
