This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package zlib1-dev has no installation candidate

Welcome to LQ. .. .. :)

Installing a new 'glib' will trash parts of Gnome etc.

1) Missing zlib ( development files ) : sudo apt-get install zlib1g-dev
( The main zlib ( run time files ) is already installed.)

2) I don't think you will need a new 'glib'.
It is installed by default. Install the missing glib parts:

sudo apt-get install libglib2.0-dev


Suggest : Make a list with the installed packages ..
dpkg --get-selections > selections.txt
