Installation of Kolab 16 on Debian 10

Warning

This document sets you up with the version of Kolab that is maintained by the community.

1. Add the following two lines to /etc/apt/sources.list.d/kolab.list:

   deb http://obs.kolabsys.com/repositories/Kolab:/16/Debian_10.0/ ./
   deb-src http://obs.kolabsys.com/repositories/Kolab:/16/Debian_10.0/ ./

2. Import the GPG key used to sign the packages:

   # wget -q -O- https://ssl.kolabsys.com/community.asc | apt-key add -
   

3. To ensure the Kolab packages have priority over the Debian packages, as must be the case for Cyrus IMAP, please make sure the APT preferences pin the obs.kolabsys.com origin as a preferred source.

   Put the following in /etc/apt/preferences.d/kolab:

   Package: *
   Pin: origin obs.kolabsys.com
   Pin-Priority: 501

4. Update the repository metadata:

   # apt-get update
   

5. Start the installation of the base package as follows:

   # aptitude -y install kolab
   

Continue to Kolab Groupware Setup.
