Simply run the following commands in the given order:

sudo apt-get autoclean
sudo apt-get clean
sudo apt-get update --fix-missing

If you still have errors, try running these commands with a better Internet connection. Sometimes, on a slow connection the packages fails to download properly.

Most likely its a problem with a cached package! Try to run

apt-get update && apt get clean && apt-get check

(You need to run this as root) This command updates your local package list, cleans the package cache, and checks for missing dependencies.

This command solves most problems with apt-get.

You list of commands might fix some apt problems, but definitely not this one. – Byte Commander Mar 15 '16 at 13:52

Launch the Software Updater. Press the Superkey (Windows key) to launch the Dash and search for Update Manager.
Check for updates. Select the tab called "Updates". ...
Install the upgrade.
