Fedora’s manual (any many other copy-paste blogs, damn) describes the following steps to upgrade system:
sudo dnf update --refresh sudo fedup download --releasever=24 --allowerasing sudo fedup reboot
Guys, don’t worry about “fedup” it’s just an alias script to “dnf system-upgrade”
I did that steps, reboot finished aaaand.. nothing! F23 on the board yet.
Sure, the post not about happy end and easy way (:
