I wasn't able to reproduce this issue on Ubuntu 15.10, npm installed fine without problems for me. Looks like it has problem finding a version of node-gyp which satisfies the version requirement, could you please attache the output of `apt-cache policy node-gyp`?
Thanks for taking your time to report this issue.
