For the benefit of @jdstrand this is how I’m building it.
I setup a lxc container and in it, installed node:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
apt install nodejs=8.11.1-1nodesource1
Install other bits to build:
apt install make g++ snapcraft
npm install --global yarn
Building the thing.
Here’s a patch I use to enable snap builds. In it we also nudge the version of electron-builder, and disable all other builds because I only need a snap. It’s snap_package_json.patch referred to below.

#!/bin/bash
rm -rf ~/.cache/snapcraft
SIGNAL_ENV=production
workdir=$(mktemp -d -p ~)
echo "Build tip of master"
cd $workdir
git clone https://github.com/signalapp/Signal-Desktop.git latest
cd latest
patch < ~/snap_package_json.patch
npm install
# Normally we use --frozen-lockfile, but as we nudge e-b version we can't do that
#yarn install --frozen-lockfile
yarn install
yarn grunt
yarn icon-gen
npm run build-release -- -l
ls $workdir/latest/release/*.snap
That should get you a working snap.
