So the question is really: why don't we have i386 packages for Ubuntu
focal?  I don't know myself and https://wiki.postgresql.org/wiki/Apt
doesn't mention any policy on that, but maybe someone from the
packaging team could comment, and if you don't get an answer here then
maybe the packaging mailing list or contacts on that wiki page could
help.

Erm.  I see now that that'd be because there is no i386 release of
Ubuntu focal.  Fair enough.  So the next question is why is this
system trying to fetch i386 stuff?  Perhaps you have multiarch
configured to fetch both i386 and amd64.  In that case I think you'll
need to change that line of sources.list to tell it that this source
doesn't have i386, like so:

deb [arch=amd64] ...
