[Icecast] Problem installing icecast2

[Steve Matzura]

I installed icecast 2.40 using the standard apt-get install command on
my Debian 8.2 (Weezie) system, but I accidentally chose the incorrect
answer to the dialog asking if I wanted to answer configuration
questions or edit the XML myself. I then removed icecast2 in the
normal 'apt-get remove' manner. I followed this by executing the
install command again. Icecast2 re-installed, but bypassed the
question I really wanted to answer, so I removed it again, but this
time I also removed the /etc/icecast2 directory, /etc/init.d/icecast2
and /etc/logrotate.d/icecast2 manually. I installed a third time,
thinking I now had a clean environment. The installation ran to
completion, but generated an error, exit status 1, from a script that
tried to chmod /etc/icecast2/icecast.xml, which did not get created
during the installation, nor did I get the question asking whether I
wanted to answer sconfig questions or edit it myself. What do I have
to do in order to make the installation ask me the question it
originally did? Or, put another way, what do I have to do to clean up
from the mess I've obviously made and start over?

Thanks in advance.
