title: Missing commands from command palette
body: <p>I've installed SublimeText 3 using following commands: </p>
  
  <pre><code>$ wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add -
  $ echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list
  $ sudo apt-get install sublime-text
  $ dpkg -l | grep sublime
  ii  sublime-text                               3176                                         amd64        Sublime Text is a sophisticated text editor for code, markup and prose
  </code></pre>
  
  <p>My goal was to install <code>CMake</code> package for syntax highlighting but I've experienced weird behavior. Following <a href="https://fritzone.wordpress.com/2015/01/14/how-to-install-syntax-highlighting-for-cmake-in-sublime-text-3/" rel="nofollow noreferrer">this tutorial</a> I've installed <code>Package Control</code> package via pasting appropriate commands to console. But after I hit <code>ctrl+shift+p</code> the only available options I see in command palette is the names of currently opened files. There is no <code>Package Control</code> nor other commands. I've found that <code>Package Control: Install</code> is available via <code>Preferences &gt; Package Control</code> menu, so I've installed <code>CMake</code> package this way. But Why I do not have any commands under command palette?</p>
