samba - Nov 2024 - Upgrading from samba version 4.20.5 to 4.21.1 using Debian Bookworm-backports

Hi
I tried to update a member server's samba version from 4.20.5 to 4.21.1
using Bookworm-backports and get the following error:

roy at moggy:~$ sudo apt upgrade
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 samba : Breaks: samba-ad-dc (< 2:4.20.1+dfsg-2~) but
2:4.17.12+dfsg-0+deb12u1 is to be installed
         Breaks: samba-ad-provision (< 2:4.20.5+dfsg) but

E: Broken packages

The following packages are installed:

So not sure why it is trying to install samba-ad-dc and samba-ad-provision as
this is a member server not a DC.    (I  tried it on another member server with
the same result).

Any advice how to proceed please?

Thanks,

Roy

I did such an upgrade last Sunday, I will do it using the command apt 
full-upgrade or apt install -t bookworm-backports samba samba-ad-dc

For a member server, you don't need samba-ad-dc or samba-ad-provision, - you
can
uninstall these just fine (probably together with samba-dsdb-modules).  Actually
you don't even have these installed, it seems - so in this your case,
I'd recommend
using `apt upgrade --no-install-recommends` (heh).

Overall, debian backports is always like this, - one have to understand how
it works. apt considers only packages already installed from bpo to be
installable
from bpo, not any new dependencies which should be *also* installed from
backports.
So in case a new dependency (or a recommendation) appears which refer to
backports,
one have to either explicitly specify `-t bookworm-backports` or resolve  the
dependencies in other ways.

Here, only new recommends has appeared, not actual dependencies, and that's
just
samba-ad-dc which you don't need anyway, - that's why
--no-install-recommends in
this particular case is ok.

On the other hand, my debian/ubuntu samba repository does not have
"NoAutomaticUpgrade: yes'
setting like backports does (you don't want to install *everything* from
backports,
just select packages, but you do want to install everything from a single
package
repository like mine, since that's the only reason you've added it). 
I'm not
suggesting to use my repo, just explaining the difference here.
