VyOS 1.1.7 on AWS?

General questions
1

Hello,

I’m trying to get a VyOS 1.1.7 AMI by firing up the last available official AMI 1.1.0 and upgrading it using

gpg --keyserver pgp.mit.edu --recv-keys 0xFD220285A0FE6D7E
add system image http://packages.vyos.net/iso/release/1.1.7/vyos-1.1.7-amd64.iso < /dev/null

but after creating an AMI from that instance, it keeps coming up with:

    Starting VyOS router: migrate rl-system firewall configure failed!

and doesn’t let me ssh in.

What’s the best way to get a working VyOS 1.1.7 AMI?

Thanks.
