The latest packages for Ubuntu are published in the saltstack PPA. If you have the add-apt-repository utility, you can add the repository and import the key in one step:
sudo add-apt-repository ppa:saltstack/salt
add-apt-repository: command not found?
The add-apt-repository command is not always present on Ubuntu systems. This can be fixed by installing python-software-properties:
sudo apt-get install python-software-properties
The following may be required as well:
sudo apt-get install software-properties-common
Note that since Ubuntu 12.10 (Raring Ringtail), add-apt-repository is found in the software-properties-common package, and is part of the base install. Thus, add-apt-repository should be able to be used out-of-the-box to add the PPA.
Alternately, manually add the repository and import the PPA key with these commands:
echo deb http://ppa.launchpad.net/saltstack/salt/ubuntu `lsb_release -sc` main | sudo tee /etc/apt/sources.list.d/saltstack.list
wget -q -O- "http://keyserver.ubuntu.com:11371/pks/lookup?op=get&search=0x4759FA960E27C0A6" | sudo apt-key add -
After adding the repository, update the package management database:
sudo apt-get update
Install the Salt master, minion, or syndic from the repository with the apt-get command. These examples each install one daemon, but more than one package name may be given at a time:
sudo apt-get install salt-master
sudo apt-get install salt-minion
sudo apt-get install salt-syndic
ZeroMQ 4 is available by default for Ubuntu 14.04 and newer. However, for Ubuntu 12.04 LTS, starting with Salt version 2014.7.5, ZeroMQ 4 is included with the Salt installation package and nothing additional needs to be done.
Now go to the Configuring Salt page.
Docs for previous releases are available on readthedocs.org.
