Upgrade Fedora 14 to Fedora 15 howto

This upgrade when smoother than any so far, did not lose any Network settings for example! This is all you need to do:

# As root you would like to have a clean start to the
# upgrade, so get an update out of the way.
$ yum update rpm

$ yum -y update

$ yum clean all

# Should a new kernel install/update require it,
# reboot before continuing with the rest.
# Then install the preupgrade package.
$ yum install preupgrade

# For console upgrade, use:
$ preupgrade-cli "Fedora 15 (Lovelock)"

# If you like gui's to upgrade, use this.
$ preupgrade

That was it, just watch the action, drink some coffee/beer and reboot when asked to. Presto change-o you now have a Fedora 15 installation!


  1. I used preupgrade and my network is broken. NetworkManager recognized my devices on the reboot into F15 the first time, but after I shut it down at night and restarted in the morning, it doesn't work. NetworkManager fails to start, nm-connection-editor won't even allow me to edit any connections. I'm using ifup to get my wired connection to work, but no luck with wireless. says that network devices changed from ethX to pXpY and those scripts in /etc/sysconfig/network-scripts don't exist for me.

  2. William,

    Sounds like something went horribly wrong... I don't have any of these pXpY stuff and ethX is still the wired connection for me.

    I am on a lenovo laptop, T500.
