Any solutions for this ?

Thanks RSA

I'm using 1.6.12 on a RasPi and I'm also getting this error. Is there a resolution for it?

3

The Arduino IDE needs access to the internet to download the Library Manager index file. It may be that your firewall or other network security settings are preventing this. Can you whitelist the Arduino IDE?

4

What do I need to whitelist?

5

"Caused by: java.net.SocketException: Permission denied: connect"

Looks like a permission problem. Try using 'sudo' to run the program with root permissions.

6

Using "Run as Administrator" might also help seeing as you are using Windows.

You can google it if you wish or see if you already have the option enabled.

7

Try using 'sudo' to run the program with root permissions.

They're using Windows, which doesn't have sudo.

8

In my case, it a RasPi.

Oops, my bad. I was looking at rsatw's post.

10

Did you try the things we suggested:

Whitelist the Arduino IDE application in your firewall software.

Run the program with root permissions.

11

Running it sudo didn't change anything.

What do I whitelist? Arduino isn't listed.

12

Probably not a firewall issue.

Borrowed a windows machine, installed the latest widows version, success.

Also installed 64 bit linux version on a Linux laptop. Success.

So it seems it's an issue with the RasPi or the Arm release.
