Upgrade Fedora 8 to Fedora 9 Using PreUpgrade

Fedora 9 was released this past Tuesday. The upgrade process has changed slightly, with the Fedora Project integrating a new tool called PreUpgrade.

To upgrade, make sure your system is fully updated with:

[code]
yum -y update
[/code]

and reboot when the process has completed successfully (in case it installed a new kernel).

From here, we can install the new PreUpgrade with:

[code]
yum install preupgrade
[/code]

When that finishes, kick it off with:

[code]
preupgrade &
[/code]

As we proceed through the wizard, your screens will resemble:

F9 Upgrade 1

Click Forward.

F9 Upgrade 2

The new release will be chosen by default. Click Apply.

F9 Upgrade 3

At this point, new packages are downloaded which may take some time. Grab some coffee while the downloads transfer.

F9 Upgrade 4

Finished! Reboot and we will see a screen like this:

F9 Upgrade 5

The remaining portion of the upgrade will be completed by Anaconda, which took approximately 5 hours on my system. Proceed by clicking Next.

F9 Upgrade 6

“Upgrade an existing installation” is preselected, hit Next to continue.

F9 Upgrade 7

Here you are prompted to upgrade the GRUB boot loader. This is the best thing to do. Click Next. The following series of screens are shown as the upgrade progresses:

F9 Upgrade 8

F9 Upgrade 9

F9 Upgrade 10

F9 Upgrade 11

Ah, here we are. We find ourselves at the final screen, indicating the success of the upgrade. Word. Reboot. And that should conclude the process.

In my opinion, this upgrade was 1000x better than the upgrade from F7 to F8. I ran into all kinds of issues then, but this was better.

Having gone through the steps now, what was your upgrade experience like?

Disable IPv6 in Ubuntu 8.04

Some may find that out-of-the-box, Hardy Heron’s network performance is painfully slow. By default, IPv6 is enabled, and chances are good that your nearest router can’t speak the language nor interpret DNS requests efficiently.

To disable IPv6, open a shell and append the following to /etc/modprobe.d/blacklist:

[code]
# disable ipv6
blacklist ipv6
[/code]

Reboot.

To verify that IPv6 is disabled, run

[code]
lsmod | grep ipv6
[/code]

or

[code]
ip a | grep inet6
[/code]

The commands shouldn’t return any information. Firefox browsing speeds should be much improved.
