Icecast - Jun 2022 - Reinstall changes icecast.xml

Ubuntu 20.04.4
Icecast 2.4.4-3ubuntu0.1

    <authentication>
        <!-- Sources log in with username 'source' -->
        <source-password>PASSWORD-A</source-password>

        <!-- Relays log in with username 'relay' -->
        <relay-password>PASSWORD-B</relay-password>

        <!-- Admin logs in with the username given below -->
        <admin-user>username</admin-user>
        <admin-password>PASSWORD-C</admin-password>
    </authentication>

Then I do apt remove icecast2 and apt install icecast2.... The icecast.xml stays
the same apart from:

    <authentication>
        <!-- Sources log in with username 'source' -->
        <source-password>PASSWORD-D</source-password>

        <!-- Relays log in with username 'relay' -->
        <relay-password>PASSWORD-D</relay-password>

        <!-- Admin logs in with the username given below -->
        <admin-user>username</admin-user>
        <admin-password>PASSWORD-D</admin-password>
    </authentication>

Are these passwords supposed to change on reinstall?  Where is it getting
PASSWORD-D from, it's nowhere else in icecast.xml??

I noticed this when I updated from 18.04 to 20.04, which meant that icecast
didn't work as expected after the update, but the same happens with
uninstall / reinstall on 20.04.

This is unhelpful when updating

this doesn't look like it is about upstream Icecast but the Ubuntu
package. Therefore best addressed at the Ubuntu bug tracker.

However: There are some Debian based packages out there that manage the
password as part of the package configuration. My best guess here is
re-installing triggered the package manager to sync it's stored
password back into the config file. If that is the case maybe it is
best to manage the password within the package manager?

Over here at Debian that is debconf. And it asks me on install if I
want to have Icecast managed by it. If I select the managed mode I get:
   $ debconf-show icecast2
   * icecast2/icecast-setup: true
   * icecast2/hostname: localhost
   * icecast2/adminpassword: hackme
   * icecast2/sourcepassword: hackme
   * icecast2/relaypassword: hackme

So maybe you can also just disable that by setting icecast2/icecast-
setup to false? But again, I would like to refer you to the Ubuntu
package maintainer/bug tracker here as all the above is guesswork based
on how things are on Debian.

Still hope that helped.


With best regards,
