My input is:
sudo apt-get install libsdl1.2-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev
and the output is:
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. libsdl-image1.2-dev : Depends: libjpeg-dev Depends: libtiff4-dev but it is not going to be installed libsdl1.2-dev : Depends: libglu1-mesa-dev but it is not going to be installed Depends: libpulse-dev but it is not going to be installed Depends: libxt-dev but it is not going to be installed E: Unable to correct problems, you have held broken packages.
How do I fix this?
