Your assessment was correct. Commenting out "search ." and then installing Postfix resulted in a successful install. ---- I'm just not sure fixing it like this is the right way though. I have and ubuntu 20.04 that didn't fail install or upgrade of postfix. And I have a friend whos on 20.10 that didn't fail install or upgrade of postfix. This seems like being a Hirsute problem. Even found this on the net. (He decided to null the man.cf file though instead of finding a solution) https://askubuntu.com/questions/1333199/apt-update-encounters-an-error- configuring-postfix-after-upgrade-to-21-04/1346306#1346306 My point being one should rather figure out why this happens. And figure out a possible fix it. Or more will probably show up with the bug.
