Hi @NicolasGoudot, thanks for reaching out. Since the installation script referenced it, what is the output of

Code: Select all

systemctl status snmptrapd.service

and

Code: Select all

journalctl -xeu snmptrapd.service

?

and of course i dont have any firewall

root@srvl-nagiosxi:~# ufw status verbose
Status: inactive
root@srvl-nagiosxi:~# iptables -L -n
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

I just think that nagios xi is very paintful, i come from Zabbix which support lastest linux distribution

Check SNMPTrap Service Status:
Run the following command to check the status of the SNMPTrap service and gather more information about the errorwordle:

systemctl status snmptrapd.service

This will provide you with detailed information about why the SNMPTrap service is failing to start.

[swolf]

Nagios XI does support Ubuntu 22.04, and most customers do not have trouble installing on that distribution. We recommend using a minimal installation for best results.

The output from systemctl indicates that another service or application is already listening on port 162. I would recommend starting from a minimal 22.04 image and running the install process again, without installing any other applications on the server.
