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:
libsdformat-dev : Depends: libboost-regex-dev but it is not going to be installed
Depends: liburdfdom-dev but it is not going to be installed
libsdl-image1.2-dev : Depends: libtiff-dev
libsdl-mixer1.2-dev : Depends: libflac-dev (>= 1.2.1) but it is not going to be installed
Depends: libvorbis-dev (>= 1.2.0) but it is not going to be installed
libsdl1.2-dbg : Depends: libsdl1.2debian (= 1.2.15-8ubuntu1) but 1.2.15-8ubuntu1.1 is to be installed

libsdl2-dev : Depends: libpulse-dev but it is not going to be installed
Depends: libudev-dev but it is not going to be installed
It seems libsdl installation was not successful. While searching about libsdl there are two versions libsdl1 and libsdl2. I am thinking to find some other ways to install them. Anyone have any advice for the installation?
@steeldriver:I did your suggestion and the output was the followings:
$ sudo apt-get update && sudo apt-get upgrade
finished...
$ sudo apt-get install libsdl1.2-dev

Solved by doug's suggestion
Open up Software & Updates > Updates tab & make sure that
the first 2 are enabled. (- trusty-security, trusty-updates).
If one or the other wasn't enabled then do so,
after that reload sources & proceed.
Thanks for your solution, doug! Thanks to all who participated in this problem especially steeldriver and A.B.!
