RHBA-2016:1022 - Bug Fix Advisory

Topic

Updated preupgrade-assistant packages that fix several bugs and add various enhancements are now available for the Extras channel of Red Hat Enterprise Linux 6.

Description

The Preupgrade Assistant is a diagnostics utility that assesses the system for possible in-place upgrade limitations and provides a report with the analysis results. It is based on a module system, with each module performing a separate test, checking for package removals, incompatible obsoletes, changes in libraries, names changes, or deficiencies in the compatibilities of some configuration files. Data gathered by the Preupgrade Assistant can be used for cloning the system. It also provides post-upgrade scripts to finish more complex problems after an in-place upgrade. The Preupgrade Assistant tool is a prerequisite for completing a successful in-place upgrade to the next major version of Red Hat Enterprise Linux.

This update fixes the following bugs:

• Previously, if the preupgrade-assistant utility was used to upgrade to Red Hat Enterprise Linux 7, the GRUB option "--location=partition" was in some cases retained. Consequently, the upgraded system could not boot, , because this option is incompatible with GRUB2. This update ensures that "--location=partition" is not carried over during the upgrade, and thus prevents the described problem from occurring. (BZ#1263244)
• Prior to this update, preupgrade-assistant always included the debug output, regardless of whether the "--debug" option was used. Now, preupgrade-assistant correctly applies the "--debug" option, which makes the resulting report easier to read. (BZ#1249074)
• When preupgrade-assistant was executed with the "--mode" option, it terminated unexpectedly with the following traceback message:

Application does not have not attribute 'path'

This update ensures that preupgrade-assistant uses the correct directory path in the described circumstances, which fixes the problem. (BZ#1317124)

• A bug caused the "preupg" command to terminate unexpectedly if the input was sent non-interactively from a UNIX pipe. Now, "preupg" is able to correctly accept input from a pipe. (BZ#1231410)

In addition, this update adds the following enhancements:

• The preupg-content-creator utility is now available in the preupgrade-assistant-tools subpackage. The utility is designed to help with kickstarting a new module for preupgrade-assistant. (BZ#1253682)
• The preupgrade-assistant utility now includes the "%packages --ignoremissing" directive. If this directive is specified, the kickstart installation automatically skips non-existent packages and logs them, instead of requesting confirmation by the user. (BZ#1261460)
• The "--select-rules" and "--list-rules" options have been added to preupgrade-assistant. "--select-rules" runs a set of contents given as a comma-separated list, and "--list-rules" lists the available contents. (BZ#1293410)
• To remain compatible with the most recent Red Hat Enterprise Linux version of OpenSCAP, preupgrade-assistant has been updated to reflect the latest XSLT files in use. (BZ#1304772)
• Previously, preupgrade-assistant was distributed as set of architecture-specific RPM packages. As this is no longer required, it is now distributed as a single cross-architecture (noarch) package. (BZ#1289939)

Users of preupgrade-assistant are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

Solution

Before applying this update, install the openscap-engine-sce package, and make sure all previously released errata relevant to your system have been applied.
