I use
apt-get update; apt-get -y dist-upgrade; apt-get -y autoremove; apt-get clean

here apt-get update is broken.
Try to use synaptic

Have you tried using another mirror in your sources.list?

Do you have a firewall blocking outgoing connections?

It's weird that apt gets stuck in that way. It would be interesting to run it under strace to know where it gets stuck. Can you run "strace -o log -f apt update" and share the log file?

There was no problem until 2-3 days ago. (max 1 weeks ago)

• Have you tried using another mirror in your sources.list?
  No

• Do you have a firewall blocking outgoing connections?
  No

• "strace -o log -f apt update" log file ( I hope it's the right one. /root/log )
  I couldn't upload the file here because its size is 32.26MIB (MAX 2.00 MİB)
  Therefore, I share the link below.

It seems to be related to the "command-not-found" package. It installs a hook into apt and that hook is blocking.

You can try to comment the configuration entries in /etc/apt/apt.conf.d/50command-not-found

we can mark the issue as resolved. Thank you @rhertzog

Well, the issue is not fixed, we have just given you a work around. Although it's not clear why it breaks for you.

Are you running on an installed system? On a live image? On a live image with persistence?

If you run it on an installed system, what filesystem are you using?

I use it as the only operating system installed on the HDD.

https://www.kali.org/news/python-2-end-of-life/ Could this be the reason?

When you run the update and upgrade command by turning off the internet connection, the update screen comes as in the screenshot, then I can get the update by opening the internet connection.

No, https://www.kali.org/news/python-2-end-of-life/ this apt and pt-get are already python 3.

I'm guessing the issue has been corrected with the current update.
