Robie any chance I could get you to sync krb5 1.17-2 from Debian
unstable to disco?
It's probably not a big deal but there's no reason not to take the fix
into Disco.

yes.

I was working with this a bit testing the upgrade from wheezy to buster
on the Debian side. Wheezy is the only Debian release that is vaguely
extant where this could come up.
In my testing, Debconf didn't actually remove the template on an
upgrade.
So, The two cases where I found that I could reproduce the situation
Were:
* remove krb5-admin-server on the old release and install it on the new
release (without doing an upgrade)
* Copy in a /etc/default/krb5-admin-server from another system.
Neither of those seems serious enough to backport a fix for. I'd rather
wait until we get a better understanding of how this gets triggered
before doing any changes to xenial. I agree though that if we need to
change any old release xenial is the only target.

Title:
krb5-admin-server postinst has broken debconf if RUN_KADMIND set in
/etc/default/krb5-admin-server
Status in krb5 package in Ubuntu:
Triaged
Bug description:
Package installation fails on postinst due to broken debconf when
/etc/default/krb5-admin-server sets RUN_KADMIND to a value.
This happens because the .config script [0] sets debconf question krb5
-admin-server/kadmind to the defaults file value when set to a value.
But the .templates file [1] has no entry for this question resulting
in a lookup failure.

This bug seems to go back to at least Xenial (and also affects debian
packaging too). We worked around this locally by removing RUN_KADMIND
from our local defaults file, but this was an annoying bug to sort out
and should probably be fixed. That said I'm not sure if it would be
more appropraite to remove the db_set from [0] or add the question
back to [1].
