Comment 5 for bug 1931801

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)

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.
