I am using Shutter screenshot tool as default screenshot tool. I installed it in my Ubuntu 10.10 Maverick Meerkat from the Shutter Team official PPA. The latest available version in that PPA is 0.86~ppa4. The PPA has not been updated for quite some time now. I wanted some bugs to be fixed and when I saw bug pages, they had already been fixed in latest revision. So, I decided to install it.
To do so, I went through the following process.
sudo apt-get install bzr libgtk2-unique-perl libimage-info-perl libimage-exiftool-perl
Get latest Shutter
bzr branch lp:shutter
cd shutter sudo cp bin/* /usr/bin/ sudo cp -R share/* /usr/share/
Now quit Shutter if you have it opened and launch it again.
