Comment 3 for bug 1730208

Ah, the description implies this happens at build time, but it actually happens at run time. I believe the issue here is that you're building on 17.10, which has a newer libc than Xenial, which is what you run against. Is there a reason you're building on 17.10? If not, you can run `snapcraft cleanbuild`, which will spin up a Xenial lxd container for building, or otherwise run Snapcraft on Xenial.
