I had the same bug. The problem appeared after a kernel update. It happens because there is no kernel module TUN. This can be checked with the following command:

$ sudo dmesg | grep TUN
[   26.091113] tun: Universal TUN/TAP device driver, 1.6

Outline needs to create a TUN interface to work properly.

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.31.1    0.0.0.0         UG    304    0        0 wlan0
10.0.85.0       0.0.0.0         255.255.255.0   U     0      0        0 outline-tun0
192.168.31.0    0.0.0.0         255.255.255.0   U     0      0        0 wlan0

If you don’t get this output, simply reboot and check again.

If it is still missing, add a TUN kernel module and reboot.

sudo modprobe tun
lsmod | grep tun
reboot

I hope it helps.
