Immediately following the download of new packages for the upgrade to Karmic Koala, I noticed it had hung up while attempting to turn off services which were going to be upgraded.
<pre>
mysql stopping...

It happened that MySQL was the hold up, and because killing the upgrade process seemed like a risky operation – I needed to find a way to move it along.
I wasn’t able to turn up any other posts from the community about this issue – so I decided to take the usual approach: Start killing process with fingers crossed and blog the outcome!
Just so happens I nailed it on the first try:
<pre>
$ ps aux | grep mysql
<snip />
root 3624 0.0 0.0 5452 1744 pts/7 S+ 09:05 0:00 /usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf shutdown
$ sudo kill -9 3624 #your pid would be different...
</pre>
The upgrader picked up and moved right along at that point. Hurray!
