[Samba] upgrade ununtu 20.04 -> 22.04 and samba 4.18 -> 4.19

>How did you upgrade ?
>If I remember correctly, both 20.04 and 22.04 come with 4.15.13 (latest Samba version available), so could it be that the upgrade from 20.04 to
>22.04 managed to install unrequired packages ?
I did a do-release-upgrade first to go from 20.04 to 22.04, and then updated my /etc/apt/sources.list.d/mjt.list to go from focal/samba-4.18 to jammy/samba-4.19. I also unmasked some services masked during upgrade.
Samba -V reports "Version 4.19.3-Ubuntu".
What files/versions should I check in addition?

If Ubuntu cannot keep its fingers off packages installed from some other repo, I´d consider that a bug and am willing to file a bug report.

>Your second option, if you must get this fixed quickly (if someone is shouting at you), demote the DC, wipe it and re-install the OS and then join it as a new DC.
I´d prefer option one but am stuck right now, hoping for suggestions.

Thanks, Joachim
