focal-backports contains debhelper 13.5.2ubuntu1~bpo20.04.1. This is an architecture-independent package, but it depends on debugedit, which is architecture-dependent.
The debugedit package exists in focal-universe for amd64, but not for i386. As a result, Launchpad is not able to build PPA packages targeting focal i386 that require debhelper-compat (= 13).
This would appear to be an oversight. It does not affect bionic, hirsuite, impish, or jammy; all of these contain the debugedit:i386 package. (It was moved from universe to main at some point after focal.)
