Hello all,
Sorry, I found a solution!
Apparently poorly studied the subject matter
You must stop the net-snmp service before making changes.
Make changes to the file
Code
systemctl stop service.net-snmp.service
nano /storage/.kodi/userdata/addon_data/service.net-snmp/share/snmp/snmpd.conf
Add line to end of file
Save it. And start the net-snmp service
Enjoy)
