Hi @engll , can you reach http://downloads.arduino.cc/packages/package_index.json by clicking the link in a browser? If it works and you still get the error from the IDE it could be a proxy/firewall related problem, and you can try adjusting the values under "Preference/Network" to match your network configuration.
Hi @facchinm , Thanks for the help. Yes, it seems like a proxy related problem. After matching proxy configuration from my browser to "Preference/Network" a dozen or so boards are showing up and the last one is "AMEL-Tech Boards by replaced by Arrow Boards", but I am still seeing the following error messages. I do have an Additional Boards Manager URL: http://static.dev.sifive.com/bsp/arduino/package_sifive_index.json which I can reach with no problem in a browser.

The new error still seems related to the main package_index, not to the additional one. Maybe your browser is also whitelisted in a local firewall or similar, while Arduino IDE is not? If you try installing a board from Board Manager, does it work or it throws another exception?
I can successfully install Intel i586 Boards . When I remove the Additional Boards Manger URL, the error messages would not appear.
I got the same error. I had to delete the tmp files in the C:\Users\xxx\AppData\Local\Arduino15 folder to make it work again.
I have the same issue on Ubuntu 17.10. I don't have any firewall or proxy enabled. Removing the files does not solve the issue.
Hi, I installed the IDE the first time, and am seeing the following error messages while trying to get into the Boards Manager. I can access the URL in my browser with no problem. I am using ubuntu 14.04, and both arduino-1.8.0 and -1.6.13 give me the same error messages.
