You might want to run 'apt-get -f install' to correct these:

                        Depends: libpng-dev (>= 1.6)
                        Depends: libpng-dev (< 1.7)

i upgraded from 16.0x to 18.04 some time ago via terminal commands, all good,, i didn't install a lot of software, pretty much nothing actually, except updating Apache and PHP. Even the GNOME Shell GUI fails.

how to fix?

i tried, "sudo apt-get install synaptic" but it's impossible to install anything, via terminal nor via ubunto software app, i download the *.deb file. it keeps complaining about "libappstream4" and etc. how is the other app called? — NaturalDemon, May 29 '20 at 17:31
using "dpkg -l" i have "libappstream3:amd64 0.9.4-1ubuntu4 amd64" installed instead of libappstream4, how to fix? — NaturalDemon, May 29 '20 at 17:49
