This issue just popped up for me after upgrading from 14.04 to 16.04.6.
Per comments #20 and #25, I changed nfs-mountd.service to include rpcbind.service to the Wants and After statements:
Wants=nfs-config.service rpcbind.service After=nfs-config.service rpcbind.service
I also added BindsTo and Wants statements to nfs-server.service:
BindsTo=rpcbind.service After=rpcbind.service
On a reboot, nfs-server service ran as expected.
