Enable Shutter Edit button on Linux
On Linux Mint and on many other debian-based distribution some features of Shutter are disabled by default. Mainly the default Edit button of shutter is disabled. To enable it you have to install some addition packages. Please follow the steps to enable it.
sudo apt-get install libgoo-canvas-perl gnome-web-photo
Now launch shutter and the Edit button will be enabled. Hope this helps.
