When I've tried to install libgtk-3-dev:
$ sudo apt-get install libgtk-3-dev

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

The following information may help to resolve the situation:

Then I've checked (and found) that ligtk-3-0 (3.10.8-0ubuntu1.2) is
pre-installed with Trisquel 7.0 BUT we have libgtk-3-0 (3.10.8-0ubuntu1) on
our belenos repository.
And here the problem is: libgtk-3-dev needs Package: libgtk-3-0
(3.10.8-0ubuntu1) but newer version 3.10.8-0ubuntu1.2 is pre-installed!
So, Why pre-installed version differs from version that available on
repository for samething (belenos)?
