Network Upgrade from 6.06 for Kubuntu Desktops (Recommended)

To upgrade from Kubuntu 6.06 to 8.04 over the Internet you can use a special mode in the server upgrade system.

  1. Enable the "dapper-updates" repository.
  2. Install the new "update-manager-core" package - dependencies include python-apt, python-gnupginterface and python2.4-apt.
  3. Run "sudo do-release-upgrade -m desktop" in a terminal window.
  4. Follow the steps on the terminal window.

Network Upgrade from 6.06 for Ubuntu Servers (Recommended)

If you run an Ubuntu server, you should use the new server upgrade system.

  1. Enable the "dapper-updates" repository.
  2. Install the new "update-manager-core" package - dependencies include python-apt, python-gnupginterface and python2.4-apt.
  3. Run "sudo do-release-upgrade" in a terminal window.
  4. Follow the steps on the terminal window.

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.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu "sh /cdrom/cdromupgrade"

Or in Kubuntu run the following command using Alt+F2:

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.
