By default, Ubuntu sends some of your information to third parties without asking you to opt-in. Follow these 6 simple steps to fix Ubuntu and restore your privacy.
1. Open Ubuntu Software Center
2. Search for unity tweak tool, and click Install
3. Type your password to install
4. When installation is finished, open Unity Tweak Tool
5. Click Search
6. Uncheck Search online sources and Show "More Suggestions"
That's it! Now when you type search terms into Dash, they won't get sent to Ubuntu or any third party companies.
If you're an Ubuntu user and you're using the default settings, each time you start typing in Dash (to open an application or search for a file on your computer), your search terms get sent to a variety of third parties, some of which advertise to you.
Ubuntu should protect user privacy by default. Since it doesn't, you can follow these steps to disable the parts of Ubuntu which are invasive to your privacy.
Note: This privacy problem only affects Unity. If you use GNOME (
sudo apt-get install gnome-shell) or any other desktop environment, or if you run an Ubuntu derivative like Linux Mint, Xubuntu, Kubuntu, etc., you won't have this problem.
