The current Calamari version 1.3.1. requires SaltStack version 2014-7. Unfortunately the packages for version 2014-x are no longer available from the official SaltStack repository.

Here is how to install Calamari and SaltStack 2014.7 on Ubuntu 14.04:

Add the Calamari repository and the key:

echo "deb http://download.ceph.com/calamari/1.3.1/ubuntu/trusty/ trusty main" > /etc/apt/sources.list.d/calamari.list
wget --quiet -O - http://download.ceph.com/keys/release.asc | sudo apt-key add -

Add the SaltStack 2014-7 PPA:

sudo add-apt-repository ppa:saltstack/salt2014-7

Update the source lists:
```
sudo apt-get update
```

Install SaltStack master and minion:

sudo apt-get install salt-master
sudo apt-get install salt-minion

Install Calamari server and clients:

sudo apt-get install calamari-server
sudo apt-get install calamari-clients

Initialize Calamari:
```
sudo calamari-ctl initialize
```

You can open the gui by calling your Calamari server in your web browser now.

If you receive an "Internal Server Error" it might be because some logfiles are not accessible. This a known issue and can be found in the ceph issue tracker. Try tailf /var/log/calamari/calamari.log and reload your browser's page. If you finde something like that in your logfile:

This issue might be solved by setting the right permissions to the log directory:

sudo chown www-data:www-data -R /var/log/calamari/

After another sudo calamari-ctl initialize the Calamari gui should be visible now.
