Package libpng12-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libpng12-dev' has no installation candidate

just install libpng-dev is OK.

[akshnataraj]

configure.sh file contained libpng12-dev package which was dropped after 16.04. Instead update:
sudo apt-get -y install libpng12-dev #for capturing png
to
sudo apt-get -y install libpng-dev #for capturing png
I think this issue can be closed now.
