Description of the bug
Today, while Backdropcms.org was having server problems, on a site accessing the "Available updates" (admin/reports/updates) page and the "Install system updates" link (admin/config/system/updates) warnings were randomly being seen:
Warning: SimpleXMLElement::__construct(): Entity: line 1644: parser error : StartTag: invalid element name in update_parse_xml() (line 426 of core/modules/update/update.fetch.inc).
This was discussed at the weekly meeting of May 14, 2026 with the thought that Backdrop is not gracefully handling when the resource server is not available and the warning does not explain what is happening.
