I have Ubuntu 20. I installed libqtcore4:i386 to use packet tracer. When I installed a lot of unmet dependencies appear.
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
libqtgui4:i386 : Depends: libpng12-0:i386 (>= 1.2.13-4) but it is not going to be installed
libqtwebkit4:i386 : Depends: libpng12-0:i386 (>= 1.2.13-4) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
When I run sudo apt --fix-broken install this error appear.
The following additional packages will be installed:
libpng12-0:i386
The following NEW packages will be installed:
libpng12-0:i386
0 upgraded, 1 newly installed, 0 to remove and 16 not upgraded.
