Programming an ATTINY 85 on a breadboard

Hi.

I am trying to achieve the above to save using UNO boards, but i am having difficulty achieving this easily. I have tried many different web sites and followed the instructions to the letter, and no matter what i do, when I enter the "BOARDS MANAGER" in the IDE, i get this message "error downloading http://download.arduino.cc/package_index.json, but here are no other clues.

As anyone seen this before?

Regards

Ray

Yes, it comes up relatively frequently. We usually blame it on network security settings such as firewall not allowing the Arduino IDE to download from the Internet.

After you get that error and click the “Close” button you should see some more detailed output in the black console window at the bottom of the Arduino IDE window. Please copy and paste that in a reply here using code tags (</> button on the toolbar).

Can you open this link in your browser:
