Introduction

This document provides instructions and notes on upgrading to Ubuntu 8.04 LTS (Hardy Heron), released on the 24th of April 2008.

Before You Start

• You can directly upgrade to Ubuntu 8.04 LTS ("Hardy Heron") from Ubuntu 7.10 ("Gutsy Gibbon") or from Ubuntu 6.06 LTS ("Dapper Drake"). This page contains instructions for both. (see UpgradeNotes)

• Before upgrading it is recommended that you read the release notes for Ubuntu 8.04 LTS, which document caveats and workarounds for known issues in this version.

If you have a version of Ubuntu other than 6.06 LTS or 7.10, please see UpgradeNotes for information on how to upgrade.

Known Problems

1. Enable the "dapper-updates" repository.
2. Install the new "update-manager-core" package - dependencies include python-apt, python-gnupginterface and python2.4-apt.

Upgrading Using the Alternate CD/DVD

Use this method if the system being upgraded is not connected to the Internet.

1. Download and burn the alternate installation CD.
2. Insert it into your CD-ROM drive.
3. A dialog will be displayed offering you the opportunity to upgrade using that CD.
4. Follow the on-screen instructions.

gksu "sh /cdrom/cdromupgrade"

kdesu "sh /cdrom/cdromupgrade"

Upgrading from a Torrent

If you're familiar with torrents and have an ISP that doesn't limit them, you can download the upgrade much more quickly. You'll also be sharing your bandwidth with other Ubuntu users and helping to reduce the load on the servers, which is especially useful on release days when the server overload causes problems. Basic instructions:

1. Download the ISO file for the alternate installation CD using the .torrent file found on http://releases.ubuntu.com
2. Mount the ISO as a drive or burn it to a physical CD
3. Follow the alternate CD upgrade instructions

Detailed instructions here and here.

Troubleshooting

Unexpected reboot hangs on boot

My experience is based on Xubuntu 6.06 to Xubuntu 8.04 but I think it is the same for Ubuntu. My update stopped suddenly and after reboot Linux kernel did boot but get hung on the process boot. Here there is how I fixed it:

1. Boot with Ubuntu 6.06 disk (in my case Alternate)
2. Select: Repair a Broken system
3. Select: Open a Rescue Shell.
4. Select: Root Partition for Ubuntu.
5. Run: dpkg --configure -a
6. Whenever the process is finished: exit.
7. Boot again into your system (now it should work)
8. Run dpkg --configure -a as root from a terminal (Ctrl+alt+f1)
9. System should be updated.
