Fedora Update Notification
FEDORA-2005-914
2005-09-23
---------------------------------------------------------------------

Product : Fedora Core 3
Name : xorg-x11
Version : 6.8.2
Release : 1.FC3.45.2
Summary : The basic fonts, programs and docs for an X workstation.
Description :
X.org X11 is an open source implementation of the X Window System. It
provides the basic low level functionality which full fledged
graphical user interfaces (GUIs) such as GNOME and KDE are designed
upon.

---------------------------------------------------------------------
Update Information:

This xorg-x11 update fixes a regression in the rpm
postuninstall script of the xorg-x11-Mesa-libGLU package
introduced in the previous xorg-x11 update.

The bug is caused due to an idiosyncracy in the rpm
package manager's spec file parser, which interepreted
some comments in the spec file as being part of a
shell script.

This update works around this rpm glitch however due to
the nature of the bug being in the postun script of
the previous update, the bad postun script will still
execute on upgrades, as it is the old buggy script
that gets executed. This will cause the upgrade of
xorg-x11-Mesa-libGLU to fail. If upgrading with yum,
you will end up having 2 copies of this package
installed.

To fully install this update and correct the problem
requires performing the following steps in order, which
will ensure multiple versions of the package are not
installed, and that future updates will work properly.

1) Run "yum update" to update to the latest packages. You
will see an error message displayed when the old rpm
package postun script is executed. This error message
is expected, do not report it in bugzilla.

2) Remove all of the old libGLU packages:
rpm -e --allmatches --nodeps --noscripts xorg-x11-Mesa-libGLU

3) Install the new fixed package:
yum install xorg-x11-Mesa-libGLU


After performing the above steps, your system should be
properly updated, and future updates should work
correctly.
