samba - Nov 2025 - Upgrade Samba 4.22 with Trixie Backports 4.23

Hi,

what would be the right way to upgrade an existing Samba 4.22 on Trixie 
with the now existing Backports to 4.23. (Thanks Michael for your work!)

When I try "apt install samba/trixie-backports" on a member server I
get
this:

Selected version '2:4.23.3+dfsg-1~bpo13+1' (Debian 
Backports:stable-backports [arm64]) for 'samba'
Selected version '2:4.23.3+dfsg-1~bpo13+1' (Debian 
Backports:stable-backports [arm64]) for 'samba'
Solving dependencies... Error!
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:

Unsatisfied dependencies:
 ?samba : Depends: samba-common-bin (= 2:4.23.3+dfsg-1~bpo13+1) but 
2:4.22.4+dfsg-1~deb13u1 is to be installed
 ? ? ? ? ?Depends: samba-libs (= 2:4.23.3+dfsg-1~bpo13+1) but 
2:4.22.4+dfsg-1~deb13u1 is to be installed
Error: Unable to correct problems, you have held broken packages.
Error: The following information from --solver 3.0 may provide 
additional context:
 ? ?Unable to satisfy dependencies. Reached two conflicting decisions:
 ? ?1. samba-common-bin:arm64=2:4.23.3+dfsg-1~bpo13+1 Depends samba-libs 
(= 2:4.23.3+dfsg-1~bpo13+1)
 ? ? ? but none of the choices are installable:
 ? ? ? - samba-libs:arm64=2:4.23.3+dfsg-1~bpo13+1 is not selected for 
install
 ? ?2. samba-common-bin:arm64=2:4.23.3+dfsg-1~bpo13+1 is selected as an 
upgrade because:
 ? ? ? 1. samba:arm64=2:4.23.3+dfsg-1~bpo13+1 is selected as an upgrade
 ? ? ? 2. samba:arm64=2:4.23.3+dfsg-1~bpo13+1 Depends samba-common-bin 
(= 2:4.23.3+dfsg-1~bpo13+1)

Shouldn't the dependencies be resolved automatically?

I tried to resolve them manually and it seemed only worked partly. 
wbinfo gets information from my domain, but getent passwd AD\username no 
longer.

So, what would be the right way? Unistalling 4.22 and then just install 
4.23?

Please, everyone, learn to use debian backports.  This is not
specific to samba, it works equally for any software you
install from bpo.

You tell apt to install just samba package from bpo13.
But samba package needs other dependencies (like samba-common-bin)
from the same bpo13.  But you didn't let apt to install other deps
from non-default repository.

Exactly, once you let apt to do its work.

apt install -t trixie-backports samba

This has been discussed to death multiple times in the past.

Tanks,

And here's anther question, which I'd love to have answer for.

*Why* people want to upgrade samba from 4.22 to 4.23 in this case?
What new features 4.23 provides which are needed, or which shortcomings
4.22 has compared to 4.23?

Thanks,

Do:

echo "deb?http://deb.debian.org/debian?trixie-backports main contrib
non-free" >> /etc/apt/sources.list

And

apt-get update &&??apt-get install -t trixie-backports samba
