Installation using repository

1. Adding repository entry

To add Erlang Solutions repository (including our public key for apt-secure) to your system, call the following commands:

wget http://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb

Alternatively: adding the repository entry manually

Add one of the following lines to your /etc/apt/sources.list (according to your distribution):

deb http://packages.erlang-solutions.com/debian raring contrib
deb http://packages.erlang-solutions.com/debian quantal contrib
deb http://packages.erlang-solutions.com/debian precise contrib
deb http://packages.erlang-solutions.com/debian oneiric contrib
deb http://packages.erlang-solutions.com/debian lucid contrib

To verify which distribution you are running, run lsb_release -c in console.

Next, add the Erlang Solutions public key for apt-secure using following commands:

wget http://packages.erlang-solutions.com/debian/erlang_solutions.asc
sudo apt-key add erlang_solutions.asc

2. Installing Erlang

Refresh the repository cache and install the erlang package.

sudo apt-get update
sudo apt-get install erlang
