Opera + Widevine + Netflix

• Here is a hack to watch Netflix on Opera with Widevine DRM support.
• Download official Opera DEB and, weirdly, remove it after installation.

   cd ~/Downloads
   sudo dpkg -i opera-stable_*.deb
   sudo apt-get autoremove opera-stable
   sudo rm -rf /usr/lib/x86_64-linux-gnu/opera
