I just made a Magenta Linux Installation video at
has a few bash files that presently work to install Tensorflow Version 0.9, Bazel and Magenta tested on both a laptop ubuntu version 15.10 and a 14.04 fresh installed server (yes it's old but I had the disk lying around)
If you are having troubles installing Magenta and for some reason the bash setup.sh file does not work on your system, looking through the code may give you some ideas for how to get it working on your system.
Would like to help out windows users by getting it going on cloud9, but it uses more data than the 2 GB free user gets (seem to need about 3Gb) and I don't think most people want to pay $19.00 / month to test out Magenta.
