You may get dependency issues which can be resolved with:

Install the Agent on a Server
To check a server install the agent e.g.
sudo apt-get install check-mk-agent xinetd
The agent is called via xinted so to allow your monitoring server to contact port 6556 add allowed IP addresses to the
vi /etc/xinetd.d/check_mk
And add IP addresses to the field:
only_from = 111.222.111.222
and set:
disable = no
Then restart xinetd:
systemctl restart xinetd
Go back to the Check_mk monitoring server and from the WATO menu choose Hosts > Create
Add the server name and IP address and choose ‘Save & Test’.
You can test that check_mk agent is responding using telnet from the monitoring server e.g.
telnet 123.123.123.123 6556
