Installation: Debian and Ubuntu

This page describes how to install sup 0.13.x on recent versions of Ubuntu and Debian.

You might want to prepend commands with sudo where root access is needed.

Install system packages

apt-get install build-essential libncursesw5-dev libncurses5-dev uuid-dev zlib1g-dev

Install Ruby, Rubygems, and Rake

• Install system Ruby: run apt-get install ruby1.9.1-full.

  Note: It is highly recommended to use Ruby 1.9.x instead of 1.8.x. But currently running sup on 1.8.7 is supported as well. In this case you'll need to install Ruby by running

  # On Ubuntu:
  apt-get install ruby1.8-full rubygems rake
  # On Debian 6.0:
  apt-get install ruby-full rubygems rake

  And replace 1.9.1 in following instructions with 1.8.

• Install Ruby via rvm or rbenv. Note that sup 0.13.x doesn't run on Ruby 2.0.

rake1.8 issue

If you're using system Ruby of 1.8, You have to do this before going for the next step:

ln -s /usr/bin/rake /usr/local/bin/rake1.8

Install sup via rubygems

gem install sup # sudo is not needed if not using system ruby
# On Debian 6.0 with ruby1.9.1-full
gem1.9.1 install sup

Rubygems PATH issue on old systems

On Debian 6.0 and lower (and other old Ubuntu systems), You'll have to manually add /var/lib/gems/1.9.1/bin to PATH environment variable. Or you'll get an command not found error when running sup.

Next step

See New User Guide.

On even older versions of Debian / Ubuntu

See this page if you're on a really old system and previous instructions still doesn't work.
