Problem

When you bake and sign the agents, you might encounter the error message "No valid signature found" on the "Check_MK Agent" service and the agent does not update.

Installing the agent manually will work but later the same message appears, when the updater runs.

Reason

Due to a bug not all agent packages get signed properly. We are aware of this an investigating the situation.

Solution

  1. Go to Setup → Agents → Windows, Linux, Solaris, AIX
  2. Do Bake → Sign → Sign 
  3. After that everything should work as normal. Give the agents some time to update though.
  4. We have observed this behavior if the steps of agent baking→ deployment→ make changes → agent baking→ deployment have been done in quick succession
