Ok, so I just downloading Elementary OS, and I love it! However, I can't seem to install Gtk+ 3.0:
ryan@DevPC-LX /media/ryan/stuff/howl/src master $ sudo apt-get install libgtk-3-dev Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: libgtk-3-dev : Depends: libgtk-3-0 (= 3.10.8-0ubuntu1.6) but 3.14.15-0ubuntu1~14.04~ricotz1 is to be installed Depends: gir1.2-gtk-3.0 (= 3.10.8-0ubuntu1.6) but 3.14.15-0ubuntu1~14.04~ricotz1 is to be installed Depends: libglib2.0-dev (>= 2.37.5) but it is not going to be installed Depends: libgdk-pixbuf2.0-dev (>= 2.27.1) but it is not going to be installed Depends: libpango1.0-dev (>= 1.32.4) but it is not going to be installed Depends: libatk1.0-dev (>= 2.7.5) but it is not going to be installed Depends: libatk-bridge2.0-dev but it is not going to be installed Depends: libcairo2-dev (>= 1.13.0~20140204) but it is not going to be installed Depends: libwayland-dev (>= 1.2.0) but it is not going to be installed Depends: libxkbcommon-dev but it is not going to be installed Depends: libxi-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages. ryan@DevPC-LX /media/ryan/stuff/howl/src master $ This kind of sucks, since my favorite text editor requires Gtk+ to run...
Bizarrely, installing gedit does work. Also, I already tried Aptitude:
