My question is very similar to Ubuntu 13.10, kernel still 3.8.0-31-generic.

Recently was updating to Saucy and the ethernet cable got unplugged. So I decided to run Software Update again, to reinstall files. It returned that "everything is up to date". But according to these command-line searches, that is incorrect. How can I install Saucy now safely?

In System Preferences in the main menu, open the application Software & Updates.

In Software & Updates, select the tab Updates, and at the bottom, click on the dropdown menu for When there are other updates: and select the option Display immediately.

After this, run Software Updates, and the dialog asking if you want to install Saucy should show up again.
