Upgrading wazuh-agent over remote is not possible

[MIPMHannes]

I used ansible to push the wazuh-agent on my servers.
I want to do the upgrading via wazuh dashboard remote upgrade function.

However upgrade fails instantly with this error code on the wazuh agent logs

wazuh-modulesd: ERROR: (1118): Could not retrieve information of file '
    /var/ossec/etc/wpk_root.pem
    ' due to [(2)-(No such file or directory)].

The relevant section in /var/ossec/etc/ossec.conf looks like this:

  <active-response>
    <disabled>no</disabled>
    <ca_store>
    /var/ossec/etc/wpk_root.pem
    </ca_store>
    <ca_verification>yes</ca_verification>
  </active-response>

No wonder it fails

You can work around it by removing newlines from the ca_store option:

  <active-response>
    <disabled>no</disabled>
    <ca_store>/var/ossec/etc/wpk_root.pem</ca_store>
    <ca_verification>yes</ca_verification>
  </active-response>

Now upgrades work again.

So the template file var-ossec-etc-ossec-agent.conf.j2 should be modified to fix this.
