The DejaVu font packages currently point to http://dejavu-fonts.org/, which is now an ad-laden parked domain. It should point to the current DejaVu project URL, https://dejavu-fonts.github.io/
Thanks for the report! This problem is fixed with many others in the builds in https://copr.fedorainfracloud.org/coprs/nim/fonts-rpm-macros/ Those builds are waiting for FPC to end reviewing https://pagure.io/packaging-committee/pull-request/934 to be pushed Fedora side (probably just in devel, given the amount of fixes and changes)
