Update fedora to upcoming versions

Make sure you system is up to date

sudo dnf --refresh upgrade

And install the system upgrade plugin for dnf

sudo dnf install 'dnf-command(system-upgrade)'

Now upgrade and download the latest release version files by running

sudo dnf system-upgrade download --releasever=33

This will be a hugo download and will take some time. After this, finally run

sudo dnf system-upgrade reboot

This command will reboot and go through the installation phase. After a successfull installation, you will be running the latest fedora version. (In my case 33.)
