Software Updater error

I am having serious trouble with setting up the ethernet connection in Ubuntu 16.04, so I thought of doing a software update and did so. It stopped halfway through with this black screen: https://isstatic.aoverflow.com/F0R0z.png

perl: warning: setting locale failed. 
perl: warning: Please check that your locale settings:

    are supported and installed on your system.

EDIT 1 : I followed what Ken Sharp said in the comment section : Does this look right now ?
