On some Linux distros you can get the following error when running start:
[2720:0425/142001.775056:FATAL:setuid_sandbox_host.cc(157)] The SUID sandbox helper binary was found, but is not configured correctly. Rather than run without sandboxing I'm aborting now. You need to make sure that /path/to/agregore/node_modules/electron/dist/chrome-sandbox is owned by root and has mode 4755.
The simplest solution is to change the permissions on the chrome-sandbox binary, as stated in the error:
sudo chown root:root node_modules/electron/dist/chrome-sandbox
sudo chmod 4755 node_modules/electron/dist/chrome-sandbox
Note that it is important to run these commands in that order, otherwise it won't work. You might also run into further permission issues when trying to update the project dependencies.
If your distro supports it, the following might work as a more permanent solution:
sudo sysctl kernel.unprivileged_userns_clone=1
If the solutions above don't work for some reason, you can always run Electron with the --no-sandbox flag, although this is definitely not recommended when loading untrusted web content.
