You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libgstreamer-gl1.0-0 : Depends: libgstreamer1.0-0 (>= 1.14.5) but 1.14.1-1~ubuntu18.04.1 is to be installed
libwebkit2gtk-4.0-37 : Depends: libjavascriptcoregtk-4.0-18 (= 2.24.2-0ubuntu0.18.04.1) but 2.22.4-0ubuntu0.18.04.1 is to be installed
netpbm : Depends: libnetpbm10 (= 2:10.0-15.3build1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
