Anyone help me with this issue.

Solution

You have wrong timezone set, fix this or use this workaround below:

Workaround

Add this to the command to apt-get commands:

-o Acquire::Check-Valid-Until=false

For example:

sudo apt-get -o Acquire::Check-Valid-Until=false update

Credits goes to here.

Edit:

If the workaround above did not work, then change your repository:

Go to Settings->Softwares & Updates and set Download from field to Main Server.

The cause of why it has happened maybe something is wrong with Indian Repository.

Check your system clock - it's most likely wrong (or timezone is incorrectly set)

[Admin]

Do you have an Internet connection, run rfkill unblock all; ip link

[Seenu S]

@hellomoto I have an internet connection and timezone also fixed. Still, the issue is coming.

[Olimjon]

I updated my answer, check whether it works.

[guiverc]

you fixed timezone you said; is the clock correct?

[Seenu S]

@guiverc Clock is correct. Restarted the system.

[Seenu S]

-o Acquire::Check-Valid-Until=false In which file Do I need to add this command?

[Olimjon]

Just do sudo apt-get -o Acquire::Check-Valid-Until=false update...

[Seenu S]

Followed your suggestion still, facing the same issue.

[DK Bose]

The Indian repos are working just fine for me.

[Olimjon]

@DKBose, in that case, maybe, OP has messed up something with his timezone or repository. The idea of "something wrong with repository" I took here: linuxquestions.org/questions/debian-26/…
