If COPR's stats are to be believed, some of you have found my cinnamon-epel repo. Please note that these packages are now available in epel-testing:
https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2023-bfed058207
To test, on top of a Server with GUI:
dnf install --enablerepo=epel-testing cinnamon xed xreader
(If you already installed from my COPR, disable/remove that repo and then try dnf distro-sync... instead of dnf install...)
Then, choose either the Cinnamon or Cinnamon (Software Rendering) desktop options in your display manager.
HTH,
