Board Manager - MessageDigest error?

[pfeerick]

This is in relation to a 3rd party board package, so there is the possibility that this is due to an invalid board package file, but here goes...

Added 'http://boneskull.com/digistump-board-index/package_digistump_index.json' to the 'additional board manager URLs' list and tried to install the 'Digistump AVR Boards' by Christopher Hiller, and I get the following MessageDigest error at the bottom of the board manager (and in the log), and the java.lang.RuntimeException message is shown in the log. I have put in a request on the Digistump forum, and notice that someone else has had issues also recently.

I am running v1.6.5 of Arduino, on Windows 7 x64, and the board package file is supposed to be 1.6.4+ compatible, the individual support files seem to download ok, and then the MessageDigest error rears it's ugly head...

Any help would be appreciated, and I happy to run any additional tests I can.

It is an error in their board package file. They forgot to specify the checksum type for one of the Tools:
"checksum": "4e8c423fde901071259d679c3aaef97cf57c5229286057e40b73ffd4daffbf7a" should be "checksum": "SHA-256:4e8c423fde901071259d679c3aaef97cf57c5229286057e40b73ffd4daffbf7a"
There is a pull request in the repository that fixes the error(https://github.com/boneskull/digistump-board-index/pull/2) but it was submitted 23 days ago and still not fixed so it might be a while. If you want to do a Boards Manager install of these boards now you can use the URL:
https://raw.githubusercontent.com/aalku/digistump-board-index/master/package_digistump_index.json
Keep in mind that this URL will not reflect future versions of the digistump packages so you will want to change the URL in your Arduino Preferences when the official one is fixed.

Closing as invalid, because upstream needs to handle this https://github.com/boneskull/digistump-board-index/pull/2

Thanks for that, I thought someone would work out it quickly!
