I get this when I try to startup signal-desktop as a normal user: $ signal-desktop Set Windows Application User Model ID (AUMID) { appUserModelId: 'org.whispersystems.signal-desktop' } NODE_ENV production NODE_CONFIG_DIR /opt/Signal/resources/app.asar/config NODE_CONFIG {} ALLOW_CONFIG_MUTATIONS undefined HOSTNAME undefined NODE_APP_INSTANCE undefined SUPPRESS_NO_CONFIG_WARNING undefined userData: /home/gem/.config/Signal config/get: Successfully read user config file config/get: Successfully read ephemeral config file Uncaught error or unhandled promise rejection: Error: /tmp/.org.chromium.Chromium.nHhTbN: failed to map segment from shared object at process.module.(anonymous function) [as dlopen] (ELECTRON_ASAR.js:166:20) at Object.Module._extensions..node (module.js:671:18) at Object.module.(anonymous function) [as .node] (ELECTRON_ASAR.js:180:18) at Module.load (module.js:561:32) at tryModuleLoad (module.js:504:12) at Function.Module._load (module.js:496:3) at Module.require (module.js:586:17) at require (internal/module.js:11:18) at Object.<anonymous> (/opt/Signal/resources/app.asar/node_modules/@journeyapps/sqlcipher/lib/sqlite3.js:4:15) at Object.<anonymous> (/opt/Signal/resources/app.asar/node_modules/@journeyapps/sqlcipher/lib/sqlite3.js:190:3) If I remount /tmp without noexec: mount -o remount,noexec /tmp Then it works. I don't want to allow any program to be able to exec in /tmp! OBTW: any chance to a source based signal solution? RGDS GARY
This seems to be an upstream bug: https://github.com/signalapp/Signal-Desktop/issues/2595
