I'm afraid something on your system is messed up, but I don't see
how this can be a bug in apt.

This should not be possible, the apt binary and libapt-private
are in the same binary package (apt), and that Depends on libapt-pkg6.0

= 2.7.11) which adds the symbol.

The autopkgtests have passed, it runs on my (Ubuntu) system, and
works fine in a clean OCI container:
