Missing gconf2 dependency (Linux deb)

[roxaneletourneau]

I had this error when installing Galleon: chmod: cannot access '/opt/Galleon/chrome-sandbox': No such file or directory
and this error when trying to start it: galleon: error while loading shared libraries: libgconf-2.so.4: cannot open shared object file: No such file or directory.

Needed to install the missing library:
sudo apt-get install libgconf-2-4
