To install Prey on Ubuntu, you have two options. The first option is to install it from the Ubuntu repository:

sudo apt-get install prey

However, I don't recommend installing Prey this way. That's because you won't get the latest version. The second option is to install Prey through the official Prey website. In my opinion, this is the best way to install Prey, as you'll get the latest version.

How to install Prey from the official Prey website

Go to the Prey website (preyproject.com). There, make an account or log in if you already have one. Then make your way to this screen: Select "Linux". A dialog box will appear asking you if you want to run the file or save it. Select "Open with Software install". Prey will install:

How to make the Prey config GUI appear

After the installation is complete, the Prey config GUI may or may not appear. If it doesn’t appear, then navigate to the prey folder in /usr/lib:

cd /usr/lib/prey

Search for python files:

find * -name *.py

I found three results: versions/1.9.0/node_modules/sqlite3/deps/extract.py versions/1.9.0/lib/conf/gui/linux/prey-config.py versions/1.9.0/lib/agent/actions/alert/linux/flash.py The one you want is prey-config.py. Open it by copying and pasting the line into the console and prepending it with 'sudo':

sudo versions/1.9.0/lib/conf/gui/linux/prey-config.py

Then the gui should appear.
