Hi,
as a last resort option you could try AT YOUR OWN RISK:

rename apt-listchanges to apt-listchanges.bak

create a dummy apt-listchanges by coping
/bin/true to /usr/bin/apt-listchanges

pray and restart your upgrade

when/if done delete /usr/bin/apt-listchanges
and rename /usr/bin/apt-listchanges.bak to /usr/bin/apt-listchanges

Just to be sure reinstall apt-listchanges

apt install --reinstall apt-listchanges

Hope this helps.

Ciao,
Tito
