Probably you're running Synaptic on Wayland with root permission.
Please restart your session without Wayland, or run Synaptic without root permission

how do I fix this?

your title is misleading. If I understand well you mistyped your password.
Anyway, it is not related to wayland, ubuntu and synaptic at all, but an authentication issue. Either sudo configuration, or X related.
You may need to run ssh with -X, probably that will solve this issue.

I did not miss type the password I check on that

Code:

lance@type40tardis:~$ ssh -X tardis

ok, so root has no access right to your X server. You can find a lot of different solutions on the net, for example:

Before Wayland one could open a terminal, su to root, and then launch /usr/sbin/synaptic.

With Wayland all I get is:

Unable to init server: Could not connect: Connection refused
Failed to initialize GTK.

Probably you're running Synaptic on Wayland with root permission.

Wayland seems to have broken many of the apps in Linux repositories. What was wrong
with traditional X.org? It "just worked".

Debian Buster on amd64x2 with 4GB RAM and 1TB HD

Even if you get in as 19.10 is EOL the repos may have been moved. You really need to upgrade to 20.04 at least. Stay on 20.04 if you don't want to upgrade every 6 months.

This reply assumes Ubuntu Linux, when the post specifically said Debian.

Also, the reply does not address the problem I posted. The problem is
that Wayland is seriously broken.

Your reply assumes I answered you and not the op.
