Arduino IDE Won't start after installation of new boards

[charleychap]

Hello,
I recently wanted to update the firmware on my ender 3 pro using an Arduino, but I have run into an error. I installed the Sanguino boards library (Using this URL:
https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
) and now the Arduino IDE won't start. I ran the debug file and took a screenshot. Here it is:

Why?

Hi @charleychap. It looks like you might have made a typo when adding the URL:

@charleychap

unknown protocol: tps

So I think the URL you added looked something like:

tps://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json

Instead of starting with https:// as intended.

To fix the problem, you can open this file in a text editor:

C:\Users\Boing\AppData\Local\Arduino15\preferences.txt

ⓘ If looking for it with your file browser or command line, note that the C:\Users\Boing\AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

You will see a line in the file that looks something like this:

boardsmanager.additional.urls=tps://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json

Correct the error in the file. So it looks something like this:

boardsmanager.additional.urls=https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json

Save the file in the text editor.

Now try starting the IDE again.

Thanks! I would have never been able to figure that out.

You are welcome. I'm glad if I was able to be of assistance.
