Step 1 » Assign hostname for the server using the below command.
[root@krizna ~]# hostnamectl set-hostname mail.krizna.com
Step 2 » Make a host entry with your IP in /etc/hosts file.
Step 3 » Now start installing packages.

I used the auto installation as guided by the group-office wiki. However, for conveniences, quoting the contents once again:
Easy installation on a dedicated Debian or Ubuntu server
This is the easiest way of installing Group-Office. With the debian packages everything is configured automatically and Group-Office updates will be installed automatically when you update your Debian or Ubuntu system.
Install Debian >= 5 or Ubuntu >=8.10
Note: All the commands here use "sudo". This is necessary on Ubuntu. If you are on Debian you can use the "su" command first and execute all the commands without "sudo".
Add the following line to /etc/apt/sources.list
deb http://repos.groupoffice.eu/ threeseven main
You can do that easily by executing the following command in the terminal:
echo -e "\n## Group-Office repository\ndeb http://repos.groupoffice.eu/ threeseven main" | sudo tee -a /etc/apt/sources.list
To authenticate the packages you need to import the public key by running the folowing commands: In ubuntu don't do this as root because you will have trouble with the gpg keyring permissions. On debian you can do this as root and omit the sudo command before the apt-key add command.
gpg –keyserver hkp://keyserver.ubuntu.com:11371 –recv-keys 01F1AE44
gpg –export –armor 01F1AE44 | sudo apt-key add –
Note: The keyservers are often very slow. If the keyserver doesn't respond you may try this one instead: hkp://pgp.mit.edu Continue reading “Group-Office installation on Debian 6.x” »
