When installing the Checkmk agent package on Linux systems, an erroneous systemd socket unit will be installed on the target system. If the affected system is actually contacted via systemd, i.e., no xinetd is installed on the system, this will lead to an inaccessible host. In order to recover from this error on affected hosts, you have to either install the newly baked agent package on the hosts manually, or, if you are using automatic agent updates, run <tt>cmk-update-agent</tt> once manually on the hosts, as it won't get triggered via agent call.
