Date: 2017jun16 Distro: Fedora OS: Linux Q. How can I upgrade to the beta of the next release with dnf? A. This probably isn't advised but I tried this on a VM and it worked. I found the files for the OS doing this: https://mirrors.fedoraproject.org/mirrorlist?repo=fedora-26&arch=x86_64 I first looked for a "beta" repo. But there wasn't one. But there was a "release" repo that had the next version (in this case 26). I downloaded fedora-release-26.rpm and installed it with:

rpm -Uvh fedora-release-26.rpm

Then I did:

dnf update

It updated about 2,000 packages.
