Public bug reported: I'm using Ubuntu-Mate 20.04 and I am trying to compile California (a calendar program) which requires libgtk-3-dev. When I try to install libgtk-3-dev I get: The following packages have unmet dependencies: libgtk-3-dev : Depends: libgtk-3-0 (= 3.24.23-1ubuntu1) but 3.24.23-1ubuntu1.1 is to be installed So I look at what versions of libgtk-3-0 are available 3.24.23-1ubuntu1 and 3.24.23-1ubuntu1.1, of which the latter is installed. So I tried to force install the older version so that it would be compatible with the dev files but it then tries to uninstall my entire Mate desktop, NOT ACCEPTABLE. Launchpad says NOT to self compile Gtk-3 because it's already installed in Ubuntu 20.04 but the version installed seems to be borked having not been compatible with the development packages making it impossible to compile anything that uses gtk-3.
