You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 gir1.2-glib-2.0 : Depends: libglib2.0-0 (>= 2.36.0) but 2.32.3-0ubuntu1 is to be installed
 libgirepository-1.0-1 : Depends: libglib2.0-0 (>= 2.36.0) but 2.32.3-0ubuntu1 is to be installed
 python2.7-dev : Depends: libpython2.7-dev (= 2.7.4-2ubuntu3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
