[SOLVED] Install jenkins on debian

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

Then add the following entry in your /etc/apt/sources.list:

deb http://pkg.jenkins-ci.org/debian binary/

Update your local package index, then finally install Jenkins:

sudo apt-get update
sudo apt-get install jenkins
