Known issues

Elastic Agent upgrade may fail with agent binary verification error

Details

During an Elastic Agent upgrade, agent binary verification may fail with the following message:

[elastic_agent][error] failed to dispatch actions, error: failed verification of agent binary: 2 errors occurred:
fetching asc file from '/opt/Elastic/Agent/data/elastic-agent-7f30bb/downloads/elastic-agent-<version>-linux-x86_64.tar.gz.asc': open /opt/Elastic/Agent/data/elastic-agent-7f30bb/downloads/elastic-agent-<version>-linux-x86_64.tar.gz.asc: no such file or directory
open /opt/Elastic/Agent/data/elastic-agent-7f30bb/downloads/elastic-agent-<version>-linux-x86_64.tar.gz.sha512: no such file or directory

This is the result of a known issue.

Impact

After upgrade, the agent status changes to Unhealthy, and Elastic Agent no longer sends data. To fix this problem:

  • If you are using Elastic Agent version 8.1.0 or earlier, continue using that version until you can upgrade directly to 8.2.x.
  • If you are using an affected version of Elastic Agent, reinstall a non-affected version.
