Debian install pack for Leiningen 2.x, as the current leiningen in debian repositories is completely outdated.
This package only put the current lein stable script of leiningen repository in the /usr/bin repository. It is suppressed on installation. For now upgrade doesen't work and I haven't set a repository up for now.
sudo dpkg -i leiningen2_2.3.2-1_all.deb
sudo apt-get purge leiningen2
