Pull Request Overview

This PR fixes the SSL certificate update command to apply only to RHEL images and introduces unit tests to cover success and failure cases.

• Updated tests in Test_YumPackageManager.py for SSL certificate issue on both RHEL and non-RHEL images
• Modified YumPackageManager.py to conditionally run the SSL fix based on the image type and adjusted error logging
• Removed the unused yum_update_client_package attribute and inlined its value for clarity

• [nitpick] There is an inconsistency in the log prefix '[YMP]' compared to other messages that use '[YPM]'. Consider unifying the prefixes for consistency.

error_msg = '[YMP] Customer environment error (Unable to auto-mitigate known issue):  [Out={0}]'.format(output)

[Copilot]

It appears the restoration of the platform function is targeting 'extract_linux_distribution_os_info', which is inconsistent with the earlier usage of 'linux_distribution'. This may lead to unexpected behavior in subsequent tests; consider restoring the correct attribute.

Suggested change

	self.runtime.env_layer.platform.extract_linux_distribution_os_info = original_env_layer_platform_linux_distribution
	self.runtime.env_layer.platform.linux_distribution = original_env_layer_platform_linux_distribution
