E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

There is above error for any command like sudo apt-get -f install. And this is update command output:

sudo apt-get update

Should I install mentioned packages like python3-xapian one by one? Is it wise? I even run command: sudo apt-get install --reinstall python3 that does not work.
