1.0.2 Minimum System Requirements
HUBzero installations require one or more dedicated physical hosts running Debian GNU/Linux 5.0.
Other distributions might theoretically work with some modification, although they would be totally unsupported.
A typical starter HUBzero installation might consist of a single physical server with dual 64-bit quad-core CPUs, 16 Gigabytes of RAM and a terabyte of disk
It is possible to run HUBzero inside of a virtual machine such as ones created by VMware and VirtualBox. While fully functional there will would significant performance and resource limitations in such an environment.

1.0.5 Source Code
You'll find most of the source code within the web root of a working hub. But you can get source code for the middleware and all other parts by installing source code via the package mechanism as follows. First, update your package mechanism to pull packages from our HUBzero machine. Edit your /etc/apt/sources.list and add the following lines:
deb http://packages.hubzero.org/deb buck main contrib non-free deb-src http://packages.hubzero.org/deb buck main contrib non-free
Then, install the hubzero archive key so that your system can verify packages from the hubzero archive. Run the following command as root:
wget http://packages.hubzero.org/deb/hubzero-signing-key.asc -q -O - | apt-key add -
Once the public key for http://packages.hubzero.org has been installed, you can request the hubzero source code for each package:
apt-get source packageName
where packageName is the desired package from the table above.
