Can't install MM on brand new Pi4

Diminished7th

@sdetweil and this is from the terminal above the checksum error, after it finishes cloning MM:

@Diminished7th fun, try this

cd ~/MagicMirror
npm remove electron
npm install electron@6.1.12

Diminished7th

@sdetweil no joy. Still getting what appears to be the same error:

pi@raspberrypi:~/MagicMirror $ npm install electron@6.1.12

> electron@6.1.12 postinstall /home/pi/MagicMirror/node_modules/electron
> node install.js

It does look like when it’s trying to download the .zip file it’s getting hung up somewhere. I tried the install 5 or 6 times and each time the download progress will “pause” at a different point, sometimes around 13%, sometimes 20% or 30%, it’ll hang there and then jump to 100%. Not sure if this means something.

Is there a way to download the file locally and install that way to ensure it’s being downloaded completely? Should I try a different version of electron?

@Diminished7th how is the pi connected to the internet?, wired, wifi?
have u rebooted your router

Diminished7th

@sdetweil it’s on wifi. I rebooted the modem and router last night during troubleshooting. I can browse the internet while it’s downloading so the internet appears to be functioning properly. I can unhook everything and wire it up to the router if you think that will help?

Diminished7th

@sdetweil your first response seems to have been correct! It appears it is some issue with the network. For some reason, it will begin to download the .zip file, but not complete it each time. It’s not that the network is going down because it doesn’t lose connection. Maybe something with the router’s firewall?

Anyways, I connected the Pi to my phone hotspot and ran the electron install, and it completed just fine and I am up and running.

If anyone else is having this issue, the telltale sign is the progress bar getting hung up before 100% and then quickly jumping to 100% and then immediately throwing the checksum error.

Thanks to @sdetweil for the troubleshooting tips! I will be marking as solved!!

EDIT: Guess I can’t mark as solved. I’ll just let the thread die. :)
