In the official telegram channel of the Russian community Fedora there was on the termination of the release of localized builds of the distribution kit, previously released under the name Russian Fedora (RFR). that the Russian Fedora project has completed its task: all of its developments are accepted into the official Fedora repositories and into the RPM Fusion repository. Russian Fedora maintainers are now Fedora and RPM Fusion maintainers, user and package support will continue as part of the main Fedora project.
Existing users of Russian Fedora 29 (Russian Fedora 30 has not been built) need to convert the installation to regular Fedora and disable the Russian Fedora-specific repositories:
sudo dnf swap rfremix-release fedora-release --allowerasing
sudo dnf swap rfremix-logos fedora-logos --allowerasing
sudo dnf remove "russianfedora*"
sudo dnf distro-sync --allowerasing
After the conversion, you need to update the distribution kit to the current version:
sudo dnf upgrade --refresh
sudo dnf install dnf-plugin-system-upgrade
sudo dnf system-upgrade download --releasever=$(($(rpm -E %fedora) + 1)) --setopt=module_platform_id=platform:f$(($(rpm -E %fedora) + 1))
sudo dnf system-upgrade reboot
