[Samba] upgrade to 4.16 failed

[Mario]

Hello guys, need help :)
Got problems with upgrade my samba domain member.
I use Louis repos for many years with success. My last upgrade was to 4.13
and now trying to switch to new repo setup

Debian 11.7

I have done everything setup according to:
http://apt.van-belle.nl/simple-repo-setup.txt
and upgrade to 4.14 is going with no problem

When I try upgrade to 4.15, changed:
/etc/apt/sources.list.d\van-belle.list
deb [arch=amd64 signed-by=/usr/share/keyrings/louis-van-belle.gpg]
http://apt.van-belle.nl/debian/ bullseye-samba415 main

#apt update and after #apt list --upgradable
I have this:

#apt update

it is showing 4.17.9 ( this is strange because i setup 'bullseye-samba415
main')

So I tried 4.16 and now:
changed /etc/apt/sources.list.d\van-belle.list
