...  As with Debian 11, a synaptic
popup asks for the super user password, but after entering root
password I get "Authentification failure".  This worked on Debian 11.

One test to try is to open a terminal, issue the su command and give
the root password, and if that is accepted, to give the command
/usr/sbin/synaptic to see what happens, and what error messages you get.

Thanks for the hint. I tried "su -c /usr/sbin/synaptic", gave the root password, and that works. To simplify things I put alias synaptic='su -c /usr/sbin/synaptic' in .bashrc .

I also tried to use sudo to call synaptic and failed:

   rprice@maria ~ sudo /usr/sbin/synaptic
   [sudo] password for rprice:
   rprice is not in the sudoers file.

I see in /etc/sudoers

   # Allow members of group sudo to execute any command
   %sudo   ALL=(ALL:ALL) ALL

so as root I ran command "usermod -a -G sudo rprice" and checked that /etc/group contained "sudo:x:27:rprice". I then tried again to call synaptic, with the same result:

   rprice@maria ~ sudo /usr/sbin/synaptic
   [sudo] password for rprice:
   rprice is not in the sudoers file.

The %sudo line in /etc/sudoers has no effect. Is there some other incantation needed in /etc/sudoers ?
