Kolab is made up of several components, each freely available and built upon the best quality Free Software. Most of the software required to deploy Kolab Groupware should already be part of your GNU/Linux distribution. The help section gives more information about the prerequisites for running a Kolab installation, as well as more detailed installation instructions.
All releases can be downloaded from mirror.kolabsys.com. See the next section for how to install Kolab on your system. Please note that the OpenPKG packages from files.kolab.org are deprecated. If you encounter any problems, please report them at issues.kolab.org.
Current stable release: 3.0
A detailed installation guide is available at docs.kolab.org. Please make sure to follow it step by step, otherwise you most likely will run into trouble.
Even though Kolab is included in some distributions, such as Debian, Ubuntu and OpenSUSE, these packages are outdated. We would like to get recent versions of Kolab upstream, but need more help to do that. Contributions are welcome.
