Thanks for your time herb_fargus. I have a feeling that if I replace the cmdline.txt with the following it will sort itself out:
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty2 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet loglevel=3 logo.nologo consoleblank=0 plymouth.enable=0
This is just to get back to the original problem of finding out why sudo apt-get update is returning the attached errors!!![0_1501816713607_File 4-8-17, 11 11 53.jpeg](Uploading 100%)
