Upgrading Fedora 26 to Fedora 27

Update software and back up your system.


Install the DNF plugin.

sudo dnf install dnf-plugin-system-upgrade

Start the update with DNF.

sudo dnf system-upgrade download --releasever=27 --best --allowerasing


This command will begin downloading all of the upgrades for your machine locally to prepare for the upgrade. If you have issues when upgrading because of packages without updates, broken dependencies, or retired packages, add the ‐‐allowerasing flag when typing the above command. This will allow DNF to remove packages that may be blocking your system upgrade.

Reboot and upgrade.

dnf system-upgrade reboot
