Comment 5 for bug 1192223

If you encounter this kind of error "gwoffice : Depends: libgranite1 but it is not installable", you might need to add Elemntary OS daily PPA which provides libgranite1 package. So, all you need to do is execute this command to solve such error:

sudo add-apt-repository ppa:elementary-os/daily
sudo apt-get update
sudo apt-get install gwoffice #repeat the installation
