This article describes how you can upgrade your Fedora 17 system to Fedora 18 with the help of the Fedora Updater (FedUp). The upgrade procedure works for both desktop and server installations.

I do not issue any guarantee that this will work for you!


1 Preliminary Note

The commands in this article must be executed with root privileges. Open a terminal and log in as root, or if you log in with a regular user, type


to become root.

Please make sure that the system that you want to upgrade has more than 600 MB of RAM - otherwise the system might hang when it tries to reboot with the following message (leaving you with an unusable system):

Trying to unpack rootfs image as initramfs...


2 Upgrading To Fedora 18 (Desktop & Server)

First we must upgrade the rpm package:

yum update rpm 

Then we install the latest updates:

yum -y update

Next we clean the yum cache:

yum clean all

If you notice that a new kernel got installed during yum -y update, you should reboot the system now:


(After the reboot, log in as root again, either directly or with the help of



Now we come to the upgrade process. We can do this with FedUp (short for Fedora Updater; FedUp replaces preupgrade which is now deprecated).

Install FedUp...

yum install fedup 

... and call it like this:

fedup-cli --network 18

Afterwards the system is being prepared for the upgrade. Afterwards, you will be asked to reboot the system:


From the boot menu, select System Upgrade (fedup).

During the reboot, the upgrade is being performed. This can take quite a long time, so please be patient.

Afterwards, you can log into your new Fedora 18 system.

use this process to upgrade from Fed16 --> Fed18 (or 19, if 18 is as bad as advertised)?

By: Neal Becker

Be sure to run

yum distro-sync

If you ever installed any packages from testing repos, this will avoid problems when running fedup

i've done everything for F17 to F21 upgrade but when the reboot happens, the upgrade progress bar progresses to some 35% and then system automatically reboots to the boot menu where again, only F17 is present. Please advise what to do ?
