Ok, got it. To reproduce the problem, before installing the snmpd package you need to have an snmp user with an uid that does not belong in the system user range. Something with an uid higher than 999. For example: root@xenial-snmpd-1710579:~# useradd -M snmp root@xenial-snmpd-1710579:~# id snmp uid=1001(snmp) gid=1001(snmp) groups=1001(snmp) root@xenial-snmpd-1710579:~# apt install snmpd Reading package lists...
