Upgrading Fedora Installation on DigitalOcean

I found this method works for me,

#Check if user is root
if [[ $EUID -ne 0 ]]; then
    echo "Sudo privileges required!"
    exit 1;
fi

dnf update
NEXT_VERSION=25
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-${NEXT_VERSION}-$(uname -i)
dnf update dnf
dnf clean all
dnf --releasever=${NEXT_VERSION} distro-sync
# dnf remove firewalld-config-standard
# dnf install system-release-server

sync

You may need to run restorecon -R / to fix any SELinux issues.
