Software updates fails or Signature is invalid

[josmon]

Hi Support Team,

I'm trying to update my system through GUI and also through command line. If do the update through it shows that the package information was last updated on 22 days back. If you do the updates through command line using apt-get update, it telling that signatures were invalid. Please refer the attachment for screen shots. What I need to do to get my system up to date.

Thanks & Regards,
Josmon
