Shutter is an excellent screenshot tool for Linux.
I have noticed that in the Shutter application under Ubuntu 10.04, the edit option remained disabled. I thought it was a bug and began searching for soultions and ended up with this one:
The edit option remains disabled because libgoo-canvas-perl package is missing. So manually install it using the following command:
$ sudo apt-get install libgoo-canvas-perl
download size is 253kB.
Additionally install one more package:
$ sudo apt-get install gnome-web-photo
download size is 44.2kB.
Bingo! shutter back in form 🙂
