Dear Amit, you should give some time to the volunteers in this list to answer you, instead of sending multiple emails. It seems that there is some missmatch in you clock(?)/date and the current time. You could google it a bit, but a workaround seems to be to add the following option "-o Acquire::Check-Valid-Until=false" in your apt-get command for example sudo apt-get -o Acquire::Check-Valid-Until=false install package On Wed, May 3, 2017 at 12:37 PM, Amit Ambekar wrote:

Is it really necessary to write about the same problem three times within such a short time? Anyway, you can try again. Please first run apt update before running apt upgrade. -- Sjoerd Mullender
