Hi, just came across this when setting up a new Ubuntu 16.04 system. I was taking the settings from a 14.04 system and my fstab line is (more or less);
//x.x.x.x/sharex /mnt/sharex cifs credentials=/home/user/.smbcredentials,iocharset=utf8,_netdev, 0 0
I was getting the same error when trying sudo mount -a until I read through man mount and saw this at about line 1024:
----------
Mount options for cifs
See the options section of the mount.cifs(8) man page (cifs-utils package must be installed).
----------
-So I installed cifs-utils with
sudo apt-get install cifs-utils
and sudo mount-a mounted the network device without any complaints. I hope this helps:)
