[Bug 1838464] [NEW] NFS volume not mounting with systemd

[Launchpad Bug Tracker]

Hello,

I'm unable to mount NFS volume at boot time with systemd. Using Ubuntu 18.04.2 LTS.
I commented out /etc/fstab entry:
#192.168.1.103:/Multimedia/Music	/mnt/nas/music/	nfs	_netdev,auto,user,vers=3	0	0

I created "/etc/systemd/system/mnt-nas-music.mount":
[Unit]
Description=NAS volume - Music
After=network.target

[Mount]
What=192.168.1.103:/Multimedia/Music
Where=/mnt/nas/music/
Type=nfs
Options=_netdev,auto,user,nfsvers=3
TimeoutSec=10

[Install]
WantedBy=multi-user.target

I enabled it with "systemctl enable mnt-nas-music.mount" so that when I run "systemctl is-enabled mnt-nas-music.mount" I obtain:
enable

But I keep obtaining this error ("systemctl status mnt-nas-
music.mount"):

 mnt-nas-music.mount - NAS volume - Music
   Loaded: loaded (/etc/systemd/system/mnt-nas-music.mount; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Tue 2019-07-30 21:23:42 CEST; 29min ago
    Where: /mnt/nas/music
     What: 192.168.1.103:/Multimedia/Music
  Process: 1530 ExecMount=/bin/mount 192.168.1.103:/Multimedia/Music /mnt/nas/music -t nfs -o _netdev,user,nfsvers=3 (code=exited, status=32)

lug 30 21:23:42 ubuntu-desktop systemd[1]: Mounting NAS volume - Music...
lug 30 21:23:42 ubuntu-desktop mount[1530]: mount.nfs: Network is unreachable
lug 30 21:23:42 ubuntu-desktop systemd[1]: mnt-nas-music.mount: Mount process exited, code=exited status=32
lug 30 21:23:42 ubuntu-desktop systemd[1]: mnt-nas-music.mount: Failed with result 'exit-code'.
lug 30 21:23:42 ubuntu-desktop systemd[1]: Failed to mount NAS volume - Music.

If I run "journalctl -b" I notice that the attempt to mount NFS volume happens before network is ready:
lug 30 21:23:42 ubuntu-desktop systemd[1]: Failed to mount NAS volume - Music.
lug 30 21:23:48 ubuntu-desktop NetworkManager[978]: <info>  [1564514628.2750] device (enp2s0): Activation: successful, device activated.

I think this is a bug.
Thanks in advance
Michele
