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:

The following packages have unmet dependencies:
 qtbase5-dev : Depends: libgles2-mesa-dev or
                        libgles2-dev but it is not installable

I traced it down to:

$ sudo apt-get install libwayland-dev

I have a mint condition (nearly ~24h without any manual changes only apt-get install) ubuntu-gnome 14.04.2 installed.

As I need to be able to use pyqt5, which depends on qt5-default, which depends on gt5base-dev I was wondering how I can fix this situation?

Can I install old versions of packages?

I 'fixed' the problem by installing an 'old' ubuntu 14.04 (no .2) - the problem does not occur anymore.
