apt-get install linux-source-4.10.0

3

cd /usr/src/linux-source-4.10.0 menuconfig->Device Drivers->Network Device Support->Universal TUN/TAP device driver support

Then save it as tun.config.

make modules, it generate tun.ko under /drivers/net/ without err, then copy it to lib/modules/4.10.0-42-generic/kernel/net/tun.ko.

And it still doesn't work. The command "modinfo tun" doesn't output anything.

Any advice about the install tun on Ubuntu 16.04?

You're probably on a VPS so you'll need to change this on your host settings.

• Login to your VPS control panel using your username and password.
• Click the ‘Manage’ button to the right of the VPS in which you want to enable tun/tap
• Under Controls -> Settings tab, click on ‘Enable TUN/TAP’
• A dialog box appears asking for confirmation, hit yes

I had this problem myself and just fixed it by doing exactly this.
