You don't need to create a tuntap interface yourself, tinc will do this
for you. So you can just omit the whole "ip tuntap add ..." line.
However, the error messages suggest that $INTERFACE is empty, which is
weird... Did you call tinc-up manually or does this also happen when you
start tinc using "tincd -n vpn -d -D"?
