Installing Kali

Following the steps shown here: https://superuser.com/questions/1644520/apt-get-update-issue-in-kali

will resolve the issue, but you may see the following error:

wget -O kali-archive-keyring_2020.2_all.deb https://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2020.2_all.deb

This is easily fixed by pulling from http rather than https

wget -O kali-archive-keyring_2020.2_all.deb http://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2020.2_all.deb

I summarized your initial post + the steps given by @niallriddell here, with credit given to you both. Thanks! I've needed this a couple of times now.

@qx-775 December 2022, your resolution worked for me nicely.

only bump is:

$ apt-get update
Get:1 http://kali.download/kali kali-rolling InRelease [30.6 kB]
Reading package lists... Done
E: Release file for http://http.kali.org/kali/dists/kali-rolling/InRelease is not valid yet (invalid for another 2h 56min 11s). Updates for this repository will not be applied.

anyone who doesn't have time to deal with windows nonsense can use this hack to move along:

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

I am getting some other error while trying to install the package through dpkg.
sudo dpkg -i kali-archive-keyring_2022.1_all.deb
dpkg-deb: error: 'kali-archive-keyring_2022.1_all.deb' is not a Debian format archive

I am getting some other error while trying to install the package through dpkg.
sudo dpkg -i kali-archive-keyring_2022.1_all.deb dpkg-deb: error: 'kali-archive-keyring_2022.1_all.deb' is not a Debian format archive dpkg: error processing archive kali-archive-keyring_2022.1_all.deb (--install): dpkg-deb --control subprocess returned error exit status 2 Errors were encountered while processing: kali-archive-keyring_2022.1_all.deb

Immediately before that command, you should have run wget http://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2022.1_all.deb, can you confirm that command executed successfully?

Thank u
