title: Installing Heroku Toolbelt on Ubuntu through a proxy
body: <p>I'm trying to install the Heroku Toolbelt on an Ubuntu machine that's connected to the internet through a proxy. I'm pretty new to Ubuntu and its settings but I managed to get connected to the internet fine. Internet seems to be working fine for just browsing and getting updates via apt-get is always successful and curl commands return what's expected.</p>
  
  <p>When I try to run the command on the Heroku Toolbelt site:</p>
  
  <pre><code>wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
  </code></pre>
  
  <p>I get some errors:</p>
  
  <pre><code>me@mypc-vb:~/Documents/stuff$ wget -qO- https://toolbelt.heroku.com/install-ubuntu.sh | sh
  This script requires superuser access to install apt packages.
