NFS URLs are not supported

I am attempting to automount a nfs file share from another osmc. I edited /etc/fstab to read:
nfs:// /home/osmc/mnt/share nfs noatime,async,rsize=8192,wsize=8192,nolock,local_lock=all,soft,retrans=2,udp 0 0

when I attempt sudo mount -a, I get:
mount.nfs: NFS URLs are not supported.


I’ve removed the nfs:// at the beginning and now get:
osmc@osmc:~$ sudo mount -a -v
/boot : already mounted
/ : ignored
mount.nfs: timeout set for Mon Jul 27 00:11:15 2015
mount.nfs: trying text-based options ‘rsize=8192,wsize=8192,nolock,local_lock=all,soft,retrans=2,udp,vers=4,addr=,clientaddr=’
mount.nfs: mount(2): Invalid argument
mount.nfs: an incorrect mount option was specified

Try taking out the addr= option.

Please post the exact fstab file you have.
