Answer 1

notice that message:
4 not fully installed or removed.
maybe you install other package failed. then the apt tool try to install them again.
so, uninstall these error package first.
sudo apt-get --force-yes remove #your-package-name#
you need to remove the 4 not fully installed or removed package first.
then
sudo apt autoremove
now, try to install the new package again.
