Installing Koala (Sass compiler) on Ubuntu 14.04 -
<p>I'm quite new with Linux, please forgive that.
I try to install the Koala package <em>koala_2.0.4_i386.deb</em>, via Ubuntu's default package manager. Here's what happens:</p>

<p>It seems, Koala can't fully install because of my version of Ruby...?
The package manager proposes to "fix" it, by erasing it.
I do have the icon in my app list, but starting it does nothing.</p>

<p><strong>Though!</strong></p>

<p>When i check my version of Ruby, this is what i get :</p>

<pre><code>ii  libruby1.9.1                                          1.9.3.484-2ubuntu1.2                                amd64        Libraries necessary to run Ruby 1.9.1

<p>I used this software a lot under Windows, and i like its friendly UI. I tried installing other solutions anyway, other problems showed up :/ So i'd appreciate a little help for installing this one.</p>
