And to get the shorter output (which I had sent to the list) I simply remove
the below, which if it is in place:
# cat /etc/apt/apt.conf

#Debug::pkgDPkgPM "on";

InstallProgress::Fancy "off";
Binary::apt::DPkg::Progress-Fancy "off";
AllowInsecureRepositories "off";

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 build-essential : Depends: libc6-dev but it is not going to be installed or
                            libc-dev
                   Depends: g++ (>= 4:6.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So, I do have issues and broken packages...

I see there is:
Investigating (0) build-essential:amd64 < none -> 12.3 @un puN Ib >

and I'll study what it means...

Thanks for looking into this.
