Workarounds are really poor. Removing software may not be an option for some users - disabling repo_gpgcheck should not be the recommended path to maintain a secure software delivery chain.
In my opinion, the introduction of dfn5daemon should have been delayed as it is not ready for prime time, there are too many issues with it.
Besides the bug presented here, 2457884 – Fails to prepare updates after two weeks (see also GNOME doesn't offer a system update in the reboot dialog) should have been blocked the release of f44 or called for reverting back to PackageKit.
In addition, there is also 2362415 – dnf5daemon-server can stuck the whole restart/shutdown process of Fedora, which was discovered before f44 release. And many more: https://bugzilla.redhat.com/buglist.cgi?quicksearch=dnf5daemon
The way the introduction of unfinished software is rushed doesn’t make f44 a smooth user experience… why not just wait 6 months and get it done properly?
