			== Applying system updates ==
			Research Computing Services strongly recommends users apply operating system updates as soon as possible. The commands used to apply system updates differ depending on the installed operating system.

			=== Ubuntu / Debian based systems ===
			Connect to the Linux system via the CloudStack console or through SSH, then:

			# Update the refresh package database: '''<code>sudo apt update</code>'''
			# Determine what packages will be updated: '''<code>sudo apt list --upgradable</code>'''
			# Apply the updates: <code>sudo apt upgrade</code>
			# You may wish to reboot the VM to apply all updates, such as when the kernel is updated: <code>sudo reboot</code>

			=== Rocky Linux / Red Hat based systems ===
			Connect to the Linux system via the CloudStack console or through SSH, then:

			# Clear any cached data in the package database: '''<code>sudo dnf clean all</code>'''
			# Apply all security updates: '''<code>dnf update --security</code>'''
			# You may wish to reboot the VM to apply all updates, such as when the kernel is updated: <code>sudo reboot</code>

			For more information, please see [https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/8/html/managing_and_monitoring_security_updates/installing-security-updates_managing-and-monitoring-security-updates#installing-security-updates_managing-and-monitoring-security-updates Red Hat's documentation].
