| * ifupdown now sets the default route metric to 100 for interfaces with no metric option set in /etc/network/interfaces. This change makes no difference for most users, but may affect a few users with complex networking requirements. If you rely on the previous default route metric of 0 (zero), edit /etc/network/interfaces and set the metric option explicitly for your interface, for example: {{{ iface eth0 inet static address 192.168.0.2 network 192.168.0.0 broadcast 192.168.0.255 netmask 255.255.255.0 gateway 192.168.0.1 metric 0 }}} |
The X.Org configuration file (/etc/X11/xorg.conf) still has InputDevice entries for the mouse and keyboard, but they are ignored now because input-hotplug is used.

| * In Ubuntu 8.04, network-manager only manages interfaces that are marked for roaming. Thus, all interfaces that were previously managed by network-manager will be set to roaming mode during upgrade. Technically, this takes any interface stanzas using the `dhcp` method with no options and that are marked `auto`, and removes them from /etc/network/interfaces. If you rely on your interfaces being started by ifupdown when the system starts up, you need to re-enable them in /etc/network/interfaces manually, or disable roaming in '''System''' -> '''Administration''' -> '''Network'''. | After upgrading to 8.10, some keys might misbehave in X.

These release notes document known issues with Ubuntu 8.10 and its variants.
System Requirements
The minimum memory requirement for Ubuntu 8.10 is 256 MiB of memory. (Note that some of your system's memory may be unavailable due to being used for the graphics card.)
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. Low-memory systems may be able to use the desktop CD to install by selecting "Install Ubuntu" from the boot menu to run just the installer, rather than the whole desktop started by selecting "Try Ubuntu without any change to your computer".
Installation
Upgrading
Users of Ubuntu 8.04 can upgrade to Ubuntu 8.10 by a convenient automated process. Users of older Ubuntu releases need to upgrade to Ubuntu 8.04 LTS first, and then to 8.10. Complete instructions may be found at http://www.ubuntu.com/getubuntu/upgrading.
X.org Input Devices
The X.Org configuration file (/etc/X11/xorg.conf) still has InputDevice entries for the mouse and keyboard, but they are ignored now because input-hotplug is used. The keyboard settings come from /etc/default/console-setup, and to change them please use sudo dpkg-reconfigure console-setup. After that, HAL and X need to restart (or just reboot your system).
After the upgrade it might happen that there are no input devices (keyboard, mouse) available under X.org at all.

After upgrading to 8.10, some keys might misbehave in X. Please make sure you have set the keyboard model as "Generic Evdev-managed keyboard" in System → Preferences → Keyboard, in the tab Layouts.
GNOME Logout Applet
The "Logout" applet, which earlier Ubuntu releases put by default at the right side of the panel does not offer the shutdown/reboot/hibernate/suspend actions any more (since they were now split out to a separate action and dialog). It is recommended that you remove this applet and replace it with the "User Switcher" applet, which now combines the previous "User switcher" and "Logout" applets.

UbuntuStudio real-time kernel support
No real-time kernel variant is available for the Linux 2.6.27 kernel included with Ubuntu 8.10. Users of UbuntuStudio 8.04 who need real-time kernel support are advised not to upgrade to UbuntuStudio 8.10.
