[Samba] Upgrade 4.19 to 4.20 defunct

4.20 has a new package samba-ad-dc (split from other binaries in previous versions) that provides DC functionality.

Before 4.20, there is a meta-package with the same name that provides compatibility before the upgrade. It is recommended to install this meta package samba-ad-dc before upgrading to 4.20, so the upgrade has all its binaries in place and all works as expected.

If your version of Samba is very old and there is no samba-ad-dc meta package, please be aware you will need to install the additional package samba-ad-dc right after your upgrade.
