The agent updater (cmk-update-agent) is no longer provided as 32bit Linux binary executable.

If you run the agent updater under a 32bit Linux system, use the plain Python script deployment option instead.

cmk-update-agent as a Python script has the following requirements to the underlying Linux system:

  • Python 3.7
  • cryptography Python module
  • requests Python module
  • pysocks Python module (for SOCKS proxy support)

Caution: Agent updater rules configured with Executable format (Linux): 32bit packaged binary will be migrated to the Script option.
Please be sure to check for compatibility before updating!
