It cannot be approved as a bug sadly
But for help I will recommend you to try to get assistance from thier Slack channel which is the best way to get it working as they have already mentioned it cannot be considered as a bug.
There are several errors due to different conditions while installing electron I will advise you maybe google out about it or try out once in thier slack.
Just for your assurance I tried out installing electron in my Debian based Ubuntu GNOME 17.10
and was successful in installing it
I would recommend you to try this command once
sudo npm install -g electron --unsafe-perm=true --allow-root
I have attached a screenshot below -
I hope this would be helpful to you
Node version - 9.11.1(Latest)
