I am running kali in a live usb stick and it happens on both of my computers.
I have reinstalled kali multiple times on the usb and it happens even on a fresh install using the latest images available.

I have googled the issue and it seems to have to do something with the computers time being wrong but i have checked and reset it multiple times in bios and os but i have found no solution. if i wait the specified time it will just reset. i have verified that i have internet access all of the solutions on the internet involving the time do not work for me.

a web solution to install NTP service does not work because Sudo apt install (xyz) does not seem to work

Package ntp is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ntp' has no installation candidate

therefore i am stuck. it was working just 2 days ago

Hi there, I was experiencing the exact same issue while running Kali off of a usb drive. I fixed the issue by setting the correct timezone and enabling NTP synchronization thru the terminal (selecting the correct timezone with the GUI didn't actually change anything). You don't need to have the ntp or ntpdate packages installed to do this.

Here's the article I referenced: https://linuxconfig.org/how-to-set-time-on-kali-linux

Essentially:

1) $ timedatectl list-timezones -to find your timezone

2) $ sudo timedatectl set-timezone Australia/Sydney -to set your timezone (replacing Australia/Sydney)

3) $ timedatectl -verify your timezone has been changed, and notice clock synch is disabled Local time: Sat 2021-01-09 14:15:11 AEDT
Universal time: Sat 2021-01-09 03:15:11 UTC
RTC time: Fri 2021-01-08 09:46:05
Time zone: Australia/Sydney (AEDT, +1100)
System clock synchronized: no
NTP service: n/a
RTC in local TZ: no

4) $ sudo timedatectl set-ntp on -turn on ntp sync

After doing this, you should notice your local machine's time and timezone are now correct (mine was initially showing the correct time, but unchanged timezone) and should be able to do the apt update

Cheers

I entered the url you posted over here

https://downforeveryoneorjustme.com/...org?proto=http

It told me kali .org is up and the problem is with me. That is what I use to check repos.

As far as ntp. It was removed from Debian testing. Which Kali is based on.

https://tracker.debian.org/pkg/ntp
https://launchpad.net/debian/+source/ntp/+changelog

I am having the exact same problem with a fresh kali 2022.3 live usb install direct from the kali iso image file.

I have tried a variety of fixes but nothing works.

I saw your post elsewhere and tried that already. Didnt work.

Update on my troubleshooting. I have reached this point----

use this command in terminal

timedatectl set-ntp on

This should fix all problems with clock and apt/

answer:-simply copy and paste this without the quotes
then edit the values to manually configure your date ""date --set="7 mar 2023 4:53:00""

I have the simplest solution here. This is what you should do
open settings and then date and time
untick the option for automatic Date and time
for time format select AM/PM
for Timezone select based on where you are and lastly manually input the present correct time in your area.

thats all
