Issue/Introduction

When updating to Messaging Gateway (SMG) 10.7.5 on the Hyper-V virtualization platform, the first attempt to download / install the update fails with a group of errors indicating a dependency failure for the hyper-v kernel modules.

The following errors may appear on the command line if updating from the CLI or in the update log if updatiing from the Control Center GUI

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Cause

This is currently under investigation.

Initial review indicates that the update to SMG 10.7.5 occurs in two phases: the first phase attempts to download and update the SMG kernel and the second phase updates the rest of the SMG packages. When the kernel version is updated in the first update phase it no longer matches the kernel version required by the hyper-v kernel modules resulting in failures in the update dependency check.

Resolution

On the Hyper-V platform the "download only" update action will fail with a dependency check. Skipping the "update download" and instead using "update install" will result in the software update being first downloaded and then installed.

The presence of these errors on the initial update attempt appear to have no effect on an SMG system successfully updated by running the update a second time.
