Installing Arduino SAMD Boards 1.6.11 with Windows fails:
Error downloading http://downloads.arduino.cc/CMSIS-4.5.0.tar.bz2

Going to http://downloads.arduino.cc/CMSIS-4.5.0.tar.bz2 gives me a 403 Forbidden error.

Tried on Arduino 1.6.13 and 1.8.0. I'm able to Install other board packages like the SAM Boards just fine.

I can install SAMD 1.6.8, but none of the newer ones. It looks like version 1.6.8 used CMSIS 4.0 and the newer ones use CMSIS 4.5.

Probably there was some sort of network error, the link seems up now. Could you please try installing SAMD core again and close the issue if it works? Thanks

[NicoHood]

I do not know why I see an http link, but it should be changed to https. Its possible in a boards json file.

[Aerospacesmith]

Thanks NicoHood. Its because the link is a http and not a https.

https://downloads.arduino.cc/CMSIS-4.5.0.tar.bz2 does work for me. It appears the link needs updated.

[facchinm]

The file should be reachable from both http and https (and it IS reachable, I just checked directly and via a proxy). Would you mind testing now (from within the Board Manager) making sure that no warning appears in the Console? Thanks

@NicoHood , we'll also update that link to https but it can't be the root cause of this issue

[Aerospacesmith]

I believe it has something to do with my work internet.
I can not access http://downloads.arduino.cc/CMSIS-4.5.0.tar.bz2
But I can access https://downloads.arduino.cc/CMSIS-4.5.0.tar.bz2

However, I can access the 4.0.0 version of CMSIS at http://downloads.arduino.cc/CMSIS-4.0.0.tar.bz2

I just tried from many clients referring to that specific server and I can confirm is not an issue on our end. I am going to close the issue but please let us know if the problem appears again. From what I see the 403 forbidden page is not provided by us but from some internal proxy. Please verify with your network administrator.

This happened again!

@VladimirAkopyan I just tried downloading the file and had no error at all. It might have been a momentary outage or else you are behind a firewall that is preventing the download.
