You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 google-chrome-stable : Depends: libappindicator1 but it is not going to be installed
 mongodb-org : Depends: mongodb-org-shell but it is not going to be installed
               Depends: mongodb-org-server but it is not going to be installed
               Depends: mongodb-org-mongos but it is not going to be installed
               Depends: mongodb-org-tools but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Solution:

sudo apt-get install --fix-broken && sudo apt-get autoremove && sudo apt-get update
