Solving Shutter Icon Not Showing at System Tray on Ubuntu

Do you find your Shutter Screenshot Tool not showing at system tray, and it quits when you close the window? If that so, then perhaps you missed a package when installing Shutter. Just install the missing package and it's done:

sudo apt-get install libgtk2-appindicator-perl

Bonus: if you want to install Shutter with minimal packages download, while having the image editing and tray icon features, just run following command:

sudo apt-get install shutter libgoo-canvas-perl libgtk2-appindicator-perl

Have fun taking screenshots! And thanks Mario Kemper for developing Shutter.
