Just a quick one here. Yesterday I was messing around inside the /usr dir and broke the dnf package manager on my Fedora Core 40 machine. Below is how I got it back into working order.
```sh
$ sudo rpm --reinstall --verbose --hash https://kojipkgs.fedoraproject.org/packages/python3.12/3.12.2/2.fc39/x86_64/python3-3.12.2-2.fc39.x86_64.rpm
