Greetings

In the process of upgrading my system I now am stuck at a point where
I don't know how to resolve the conundrum.

/bin/sh: 1: /usr/bin/apt-listchanges: not found
E: Sub-process /usr/bin/apt-listchanges --apt || test $? -lt 10
returned an error code (1)
E: Failure running script /usr/bin/apt-listchanges --apt || test $? -lt 10

when I go to look at the files and folders in /usr/bin/ I can find
this apt-listchanges but somehow the apt 'system' isn't seeing it or
is seeing it poorly.

When I try apt --fix-broken install I the same message.

How do I resolve this - - - - -please?

TIA
