Bug description

Building Signal-Desktop dependencies fails before completing.

See note at the bottom

Steps to reproduce

• Be on Arch Linux
• clone Signal-Desktop
• run yarn install

Actual result: output

It appears to be trying to set the locale to C.UTF-8, which Arch does not have:

success Already up-to-date.
$ electron-builder install-app-deps && rimraf node_modules/dtrace-provider
electron-builder 19.46.3
Rebuilding native production dependencies for linux:x64
Rebuilding native dependency spellchecker
Rebuilding native dependency websocket
Error: /usr/bin/node exited with code 1
Output:
yarn run v1.3.2
$ node-gyp rebuild
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.

Error output:
/bin/sh: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)
sh: warning: setlocale: LC_ALL: cannot change locale (C.UTF-8)

Expected result: Installing dependencies completes without error

Platform info

Operating System: Arch Linux on 4.13.12-1-ARCH

Note: This appears to be related to a bug in electron-builder, but I'm filing an issue here since it directly impacts building Signal.

the electron-builder people fixed this earlier today; bumping electron-builder up to 19.47.0 should fix it.

Can confirm the same issue occurs on Solus. I went ahead and have our package script upgrade to electron-builder@19.51.0 and haven't noticed any issues during testing.

Prodding @scottnonnenberg about maybe treating this with a bit of priority, please? ❤️
