If you are running Nexenta Core Platform (NCP) 3.x and have been on a different planet for a few months, you may not have heard that NCP was discontinued and Illumian was created to take its place. The nexenta.org website has since been repurposed and there were some problems with the previous community hosted apt.nexenta.org. This is somewhat unfortunate for anybody that is still running NCP3 with a need for the original package repository. At Nexenta Systems, Inc. request, I have agreed to host the retired NCP3 repository for the community. For anyone still running NCP3 systems that have need of these bits, you can add the following line to your /etc/apt/sources.list file in place of any apt.nexenta.org lines:

deb http://apt.zpool.org/ncp3 hardy-unstable main contrib non-free

I no longer host this repository as it’s been several years now since NCP was discontinued. Generally speaking it’s not safe to continue running unsupported/outdated operating systems. If you are still using NCP, I would encourage you to look at SmartOS or OmniOS depending on your use case.
