Not sure F30 is supported yet, but there's apparently a couple of dependency problems with glassfish-jax-rs-api and eclipse-linuxtools-dockeras currently released. I installed F30 from the MATE_Compiz spin. Things went fine for a couple of weeks until this happened a couple of days ago: # yum -y update --skip-broken RPM Fusion for Fedora 30 - Free tainted 66 kB/s | 71 kB 00:01 Failed to synchronize cache for repo 'rpmfusion-free-tainted' RPM Fusion for Fedora 30 - Nonfree tainted 76 kB/s | 71 kB 00:00 Failed to synchronize cache for repo 'rpmfusion-nonfree-tainted' Ignoring repositories: rpmfusion-free-tainted, rpmfusion-nonfree-tainted Last metadata expiration check: 0:14:23 ago on Wed 13 Mar 2019 08:15:31 PM CDT.
