vim is already the newest version (2:7.4.1689-3ubuntu1.3).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
python3 : Depends: dh-python but it is not installable
python3-setuptools : Depends: python3-pkg-resources (= 20.7.0-1) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
further tried to run apt-get -f install vim but again same error.
