So I installed this using
dnf -y install oracle-epel-release-el9
However it seems to be broken. For example "dnf install zvbi" fails telling me no suitable package. However if I jump on a genuine RHEL9 system with EPEL setup and do the same It will install just fine and "dnf info zvbi" tells me it's an EPEL package.
In case anyone is wondering zvbi is a prerequisite for ffmpeg from RPM fusion which again installs happily on a genuine RHEL install but gives a whole slew of errors on Oracle Linux 9.
Seems odd that a week later that the Oracle mirrors of EPEL would still be out of date?
