It fails trying to install gcc it looks like. I’ve got the logs from ProffieConfig, I couldn’t find out where to find similar logs from Arduino IDE, but the same issue does occur there too.

I’m not sure if this is intentional and that 3.6 isn’t meant to be used anymore, but I was holding off on 4.6 due to some of the size issues and other weirdness when it was initially introduced. Not sure how much of that has been fixed yet…
I looked through and it looks like each of the download links (in the JSON) are fine though, so I’m not sure why it’s 403’ing. I don’t have the knowledge to trace the program(s) to know where exactly it’s pulling from. I suppose I also don’t really understand what I’m looking at though. It doesn’t seem very complicated, but I don’t know anything about Arduino’s setup.
