Installation of Kolab 16 on Debian 10¶

Warning

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

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/ ./

Import the GPG key used to sign the packages:

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

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
```
Update the repository metadata:
```
# apt-get update
```
Start the installation of the base package as follows:
```
# aptitude -y install kolab
```
