I followed the Fedora Docs and can't upgrade my Fedora to 27. After I tried this https://www.if-not-true-then-false.co... and nothing happened.

When the system reboot and I log in I always have the notice that there is a new Fedora version available and important SO and application updates. No error messages, the process seems to flow correctly.

Does someone know how to "fix this issue"? Or maybe it's better I just download the 27 and install as a new SO in my machine?

Right after reboot, check your /var/log/dnf.log , that should contain any errors. There was a bug with DNF that for some reason caused the update system to fail due to a missing internet connection, see here: https://bugzilla.redhat.com/show_bug....

If your error messages were the same, you should be able to get the newest version of DNF like this:

dnf update --enablerepo=updates-testing dnf dnf-plugins-extras

And then try the upgrade again.

I am placing this is an answer as there is not enough space allocated in the comment, which is where it should go.

Sometimes those how to's are incomplete. So wrote my own. Follow them and let us know if anything goes wrong (error messages and such): "#" means root.
