I hope you now you got the basic idea about what is Kolab and what it does actually. Now, we’ll see how to install it.

Install Kolab On Ubuntu

Kolab can be installed on all modern Linux operating systems such as Debian, Ubuntu, CentOS, RHEL, and SUSE/OpenSUSE.

In this tutorial, let us see how to install Kolab groupware in Ubuntu 14.04 LTS server.

Switch to the root user using command:

sudo su

Search for Kolab GPG key using command:

gpg --search

Sample output:

As you see below, there is one key available. So, just enter “1” to get the key.

 gpg: searching for "" from hkp server
 (1) Kolab Development Coordination Mailing List <>
 2048 bit RSA key 446D5A45, created: 2014-08-20
 Keys 1-1 of 1 for "". Enter number(s), N)ext, or Q)uit > 1
 gpg: requesting key 446D5A45 from hkp server
 gpg: /root/.gnupg/trustdb.gpg: trustdb created
 gpg: key 446D5A45: public key "Kolab Development Coordination Mailing List <>" imported
 gpg: no ultimately trusted keys found
 gpg: Total number processed: 1
 gpg: imported: 1 (RSA: 1)

Now, import the key using command:

gpg --export --armor | apt-key add -

Update the source list:

apt-get update

Install Kolab collaboration suite using command:

apt-get install kolab

During installation, you’ll be asked to setup the MySQL root user password.

root@server: -home-sk_001

Re-enter the password:

root@server: -home-sk_002

Next, we need to configure the Postfix mail server. Click Ok to continue.

root@server: -home-sk_003

Select the type of postfix mail configuration. I go with defaults.

root@server: -home-sk_004

Enter your System FQDN:

root@server: -home-sk_005

That’s it. Kolab groupware has been installed.

Setup Kolab

Run the following command to set up Kolab Groupware:


The installer will ask you series of questions. Answer them accordingly.
