These release notes document known issues with Ubuntu 8.04 LTS and version 8.04 of Kubuntu and Xubuntu.

System Requirements

The minimum memory requirement for Ubuntu 8.04 is 384MB of memory for desktop CDs, and 256MB for other installation methods. (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 database, Java, equation editor support

iSCSI partitions



Users of Ubuntu 7.10 or Ubuntu 6.06 LTS can upgrade to Ubuntu 8.04 by a convenient automated process. Users of other Ubuntu releases should upgrade step by step (e.g. 6.10 -> 7.04 -> 7.10 -> 8.04 LTS). Complete instructions may be found at

When "complex character input" is enabled, either by hand using the language-selector tool or as a result of using a CJK locale, fontforge does not respond to the keyboard. It is believed that this is a bug in fontforge, not related to SCIM. As a workaround, you can run fontforge from a terminal using the command unset XMODIFIERS; fontforge.
