Ubuntu 16: google-chrome-stable : Depends: libappindicator1 but it is not going to be installed
Solution 1:
You can run sudo apt-get -f install, as suggested by the error message. This should install any needed dependencies and resolve the issue. (Alternatively, you could use Synaptic, Aptitude, or another package manager to resolve the dependency issue.)
As @grooveplex pointed out, the -f stands for --fix-broken, not "force", and should not cause any damage to your system.
