I have the same problem. It looks like the changed server configuration breaks it. The xml file can be download, and the files referenced in it to. curl http://linuxdownload.adobe.com/linux/x86_64/repodata/repomd.xml But using the debug mode of dnf shows: LANG=C dnf update -v Cannot download 'http://linuxdownload.adobe.com/linux/x86_64/': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried. It looks like, dnf try to list the directory content. It only fails since ca. 4 days. Using fedora 26 with all updates.
