RHBA-2010:0406 - Bug Fix Advisory

Topic

Updated up2date packages that fix a bug that prevented synchronization and
rollback of multi-architecture packages across systems and fix another bug
that prevented up2date working when Red Hat Enterprise Linux 4.8 was run as
a KVM and Flex guest is now available.

Description

The Red Hat Update Agent, up2date, automatically queries the Red Hat
Network servers and determines which packages need to be updated on your
machine.

This update includes the following bug fixes:

• during package synchronization across systems, a list of all available

packages was generated and then checked for incompatible architectures (it
was and is also checked for packages that might be available via other
channels). This process did not take account of multi-architecture packages
properly. As a consequence, when syncing package profiles between two
systems, if the source profile had multi-architecture packages installed,
syncing failed with the error:

Failed: Some of the packages requested are not available.

With this update, up2date now accounts for multi-architecture packages
properly and synchronizations and rollbacks proceed properly, as expected.
(BZ#577852)

• previously, up2date did not check if it was running on a KVM-based

virtualized instance of Red Hat Enterprise Linux 4.8. Consequently, when
rhn_register ran on such an instance, registration with the Red Hat Network
failed, often with an error:

Insufficient Software Channel Entitlements

With this update, up2date now checks for and supports running in
fully-virtualized environments, allowing KVM-based virtualized Red Hat
Enterprise Linux 4.8 instances to register with the Red Hat Network and
operate as Flex Guests. (BZ#580194)

Note: the error noted above did not always appear and was misleading in
most instances in any event, since it could appear even when there were
sufficient Channel Entitlements.

For information on Flex Guest Entitlements on the Red Hat Network see
http://kbase.redhat.com/faq/docs/DOC-17424

For information on virtualized Red Hat Enterprise Linux registration on the
Red Hat Network see http://kbase.redhat.com/faq/docs/DOC-9933

All up2date users should install these updated packages which addresses
these issues.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
