Fleet and Elastic Agent 8.6.2

Details
A known issue in Elastic Agent may prevent live query results from being available in the Kibana UI even though the results have been successfully sent to Elasticsearch. For more information, refer to #2066.

Impact
Be aware that the live query results shown in Kibana may be delayed by up to 5 minutes.

Details

A panic occurs because the Elastic Agent does not have a fleet.server in the fleet.enc configuration file. When this happens, the agent fails with a message like:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x557b8eeafc1d]
goroutine 86 [running]:
github.com/elastic/elastic-agent/internal/pkg/agent/application.FleetServerComponentModifier.func1({0xc000652f00, 0xa, 0x10}, 0x557b8fa8eb92?)
...

For more information, refer to #2170.

Impact

To work around this problem, uninstall the Elastic Agent and install it again with Fleet Server enabled during the bootstrap process.

Details
This issue occurs on MacOS Ventura when Full Disk Access is not granted to the application that runs the installation command. This could be either a Terminal or any custom package that a user has built to distribute Elastic Agent.

For more information, refer to #2103.

Impact
Elastic Agent will fail to install and produce "Error: failed to fix permissions: chown elastic-agent.app: operation not permitted" message. Ensure that the application used to install Elastic Agent (for example, the Terminal or custom package) has Full Disk Access before running sudo ./elastic-agent install.

Details
A known issue in Elastic Agent may prevent upgrades scheduled to execute at a later time from running. For more information refer to #2343.

Impact
Kibana may show an agent as being stuck with the Updating status. If the scheduled start time has passed, you may force the agent to run by sending it any action (excluding an upgrade action), such as a change to the policy or the log level.

Details
Fleet will ignore any custom server.* attributes provided through the custom configurations yaml block of the intgration. For more information refer to #2303.

Impact
Custom yaml settings are silently ignored by Fleet. Settings with input blocks, such as Max agents are still effective.
