Issue with 'sudo dpkg --configure -a' and samba installation

I’ve been trying to install Samba on my Raspberry Pi, but seem to have created a broader issue in the process.

The steps to the issue were the following:

• I ran the install code:
  sudo apt-get install samba samba-common-bin

• The install got stuck after a while, on the following message:

Setting up samba (2:4.9.5+dfsg-5+deb10u1+rpi1) …
Samba is not being run as an AD Domain Controller: Masking samba-ad-dc.service
Please ignore the following error about deb-systemd-helper not finding those services.
(samba-ad-dc.service already masked)

• Now, I can’t install anthing, nor remove the partial samba install. Any attempt ends in

E: dpkg was interrupted, you must manually run ‘sudo dpkg –configure -a’ to correct the problem.

• Running the suggested command leads me back to the samba error message above.

• I have tried all I could find online. Those had no effect:
  sudo apt-get -f install
sudo apt-get clean
  Nor did killing the four processes running that refer to smbd.

• The only thing that seemed to change something was
  sudo dpkg --clear-selections

• However, as soon as I launch any install after that, such as
  sudo apt-get upgrade
  I end up back in the same loop.

• I also tried removing samba with
  sudo apt-get remove --purge samba, but it went back to the same loop too.

I can live with not installing samba, but not being able to install anything is more of a problem. Anyone who could help me solve the issue? Thanks!
