Ok, here is what I had to do in xenial to get the warning to disappear without any new errors:
Edit /etc/default/snmpd: - comment the "export MIBS=" line: #export MIBS= - remove ",mteTrigger,mteTriggerConf" from the SNMPDOPTS line: SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /run/snmpd.pid' - install snmp-mibs-downloader. It will download a bunch of MIBs in its postinst: sudo apt install snmp-mibs-downloader - restart snmpd: sudo service snmpd restart Could you guys please test this, and let me know if it fixes the original problem for you, which was "SNMPD defaultmonitors not working"?
