These release notes document known issues with version 7.04 of Ubuntu, Kubuntu and Edubuntu.
System Requirements
The minimum memory requirement for Ubuntu 7.04 is 256MB of memory. With only the minimum amount of memory available, the installation process will take longer than normal, but will complete successfully, and the system will perform adequately once installed.
Installation
Please ensure your system meets the minimum [system requirements] before installing.
- On the alternate or server CDs, creating LVM logical volumes will take some time to complete and may appear to have stopped completely. There is no need to take any action, the installation will continue after approximately three minutes for each volume configured. Bug# #105623.
- On the alternate CD, Expert mode cannot be selected from the menu as in previous releases. Instead, press F6 and type "priority=low", adding it to the kernel command-line. This will cause the full set of questions to be asked. Bug#107220.
- On the alternate CD, the Bosnian, Croatian, and Slovenian keyboard layouts are incorrect. Users of these keyboard layouts are advised to select the U.S. English keyboard layout temporarily in order to complete the installation. Once you have rebooted into the installed system, the keyboard can be reconfigured to your preferred layout by running 'sudo dpkg-reconfigure console-setup' and then 'sudo dpkg-reconfigure xserver-xorg' from a terminal window. Bug# #93077.
- On the Xubuntu desktop CD, installation may fail during partitioning with a warning such as "The ext3 file system creation in partition #1 of IDE1 slave (hdb) failed". Bug #107259. To workaround this, close the installer and follow the following steps:
- Go to Applications -> Settings -> Settings Manager.
- Select "File Manager".
- Switch to the "Advanced" tab.
- Click on the "Configure the management of removable drives and media ...".
- Uncheck both "Mount removable drives when hot-plugged" and "Mount removable media when inserted".
- Close all the windows just opened, and restart the installer.
- On the SPARC server CD, keyboard selection defaults to the obsolete Sun Type 4 model, which should not be used. Select the "Generic 105-key (Intl) PC" option instead. #105595
Upgrading
Users of Ubuntu 6.10 can upgrade to Ubuntu 7.04 by a convenient automated process. Complete instructions may be found at www.ubuntu.com/getubuntu/upgrading.
All updates for Ubuntu 6.10 should be installed before attempting the upgrade. You may ensure that you have all updates installed by following these steps:
- Go to System -> Administration -> Software Sources. If you have a previous version of Ubuntu installed, you should upgrade to each newest version in turn, following the upgrade notes for each newer version.
- Click "Check"
- Click "Install Updates"
- Wait for the process to complete
- Click"Close"
- Start Update Manager again to begin the upgrade to 7.04
- Update Manager may fail with an "Authentication failed" message, as shown below:
- Users who have serial consoles, or have made custom changes to the /etc/inittab file or files in the /etc/event.d directory should be aware that the format of these files have changed slightly and your changes will not be automatically migrated. Bug #89314. The following changes should be made.
- "respawn COMMAND" should be changed to "exec COMMAND" with "respawn" on a seperate line.
- "on EVENT" should be changed to "start on EVENT"
- the "runlevel-X" events should be changed to "runlevel X"
- Users of the LILO boot-loader with a root filesystem managed by software RAID (mdadm), LVM or EVMS will need to migrate part of the configuration manually before rebooting, otherwise the machine will fail to mount the root filesystem. Bug #105631. Edit /etc/lilo.conf and copy the "root=" line to the end of the "append=" line, so you will have "append=root=...".
- Update Manager may incorrectly calculate the free space requirements when symlinks are used for some directories such as /var/cache/apt/archives. Bug #106804. As a workaround, modify /etc/apt/apt.conf and add the following line giving the correct path for that directory rather than using a symlink.
Dir::Cache::archives "/path/to/your/apt/archives";
- If you have configured network interfaces by hand using /etc/network/interfaces, those interfaces will be ignored by Network Manager. When only those interfaces are active, the icon will still be the "Connected" icon (no matter whether those are up or down) and the tooltip will say "Manual network connection". Clicking the icon will allow you to reconfigure your networking; if you wish the interface to be managed by Network Manager, select it as "Automatic configuration (DHCP)" and ensure that the box next to the interface is checked.
