Well, as I had not got a response yet, I thought I might test the waters and attempt to install apt_2.6.1devuan1_amd64. It required a dependency, libc-bin_2.36-9+deb12u7_amd64, so I found and installed that, too.
I figured, hell, it's been awhile since I really messed up my system and had to rebuild, and I already have a mess now. But installing these didn't make any change. When I try to use apt, I still get that same error message:
sudo apt-get -f install apt-get: symbol lookup error: /usr/lib/x86_64-linux-gnu/libapt-private.so.0.0: undefined symbol: _ZN11pkgDepCache24IncreaseActionGroupLevelEv, version APTPKG_6.0
The missing symbol should be in file: /usr/lib/x86_64-linux-gnu/libapt-pkg.so.6.0 which comes from package libapt-pkg6.0:amd64 which our earlier "dpkg -l" told us was installed so let's have dpkg verify it:
dpkg -C dpkg -V libapt-pkg6.0:amd64
