During Fedora IoT installation, the anaconda-webui review screen (anaconda-screen-review) fails when attempting to query the PartitioningMethod D-Bus property.

Proposed as a Blocker for 45-beta by Fedora user pwhalen using the blocker tracking app because: "The installer must run when launched normally from the release-blocking images."
AGREED AcceptedBetaBlocker Discussed at the 2026-08-24 (blocker / freeze exception) review meeting: This is accepted as a clear violation of all "complete an installation" criteria for the release-blocking IoT installer, e.g. "The installer must be able to complete an installation to a single disk using automatic partitioning." https://meetbot-raw.fedoraproject.org//blocker-review_matrix_fedoraproject-org/2026-08-24/f45-blocker-review.2026-08-24-15.59.log.txt
The cause for this should be fixed by https://bodhi.fedoraproject.org/updates/FEDORA-2026-b3be695f76 But the IOT installer was adjusted to use GTK for Fedora 45. https://bodhi.fedoraproject.org/updates/FEDORA-2026-c8b6613fbe
