+# Known issues
+#### Recently debian added the user "Debian-snmp" to the snmp.service but for SMART/LVM Status we need the root user.
+#### edit snmpd.service and replace "Debian-snmp" with "root"
+```
+nano /lib/systemd/system/snmpd.service
+...
+ExecStart=/usr/sbin/snmpd -Lsd -Lf /dev/null -u root -g Debian-snmp -I -smux,mteTrigger,mteTriggerConf -f -p /run/snmpd.pid
