After changing the repository i ran in to a error.
While people on the forum ginving some different options, this one worked for me.
`wget https://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2018.1_all.deb`
`sudo apt install ./kali-archive-keyring_2018.1_all.deb`
Everything looks fine now. Let’s check for the final.
`sudo apt-get update`
