password prompt for network share during boot screen does not react to text input

[Daniel Holz]

After upgrading from trusty to xenial on reboot a password prompt for my network share appeared. Unfortunately I could not enter anything. To fix it I had to use a live usb stick to remove the entry I created for it in /etc/fstab.

The network share did not cause any problems with trusty and did not use a password.
