We were unable to download the installation bundle.

We were unable to download the installation bundle.

Ideally, only the available versions should be listed.

With #179 we have now (or will have very soon) builds for R 3.3.0 - 3.3.2 for all (currently) supported platforms, I believe.

CentOS 8 seems to be working in general as well.

OTOH I agree that it would be nice to have a list of versions that are actually available, because build failures might happen in the future as well.

Or we can make sure that all versions are available currently for all platforms, and also make sure about this every time a new release happens, and when we add a new platform.
