Part 1 - Lab Setup: Azure WAF Security Protection and Detection Lab

Hi Team, so run into an issue here with the apt-get command it threw this error:

svradmin@VM-Kali:~$ sudo apt-get update
Get:1 http://kali.download/kali kali-rolling InRelease [30.6 kB]
Err:1 http://kali.download/kali kali-rolling InRelease
The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <Email address removed>
Reading package lists... Done
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://kali.download/kali kali-rolling InRelease: The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <Email address removed>
W: Failed to fetch http://http.kali.org/kali/dists/kali-rolling/InRelease The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <Email address removed>
W: Some index files failed to download. They have been ignored, or old ones used instead.

So in order to resolve this, i had to run this:

# download
wget http://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2022.1_all.deb
# install
sudo dpkg -i kali-archive-keyring_2022.1_all.deb
# remove downloaded file again
rm kali-archive-keyring_2022.1_all.deb
# update
sudo apt-get update

thanks
