How to install Cloudflare WARP on Kali Linux

Surely for experienced Linux admins and experts this is easy question, but for beginners (as for me) it might be helpful.

What we have: Kali Linux 2021.2

What we want: Cloudflare WARP

Let's try to install: sudo apt install cloudflare-warp

And we get an error: E: Unable to locate package cloudflare-warp

This means that repository does not have needed package.

Let's install needed repository using the instructions from https://pkg.cloudflareclient.com/install article.

1. Check the Debian version of Kali Linux

cat /proc/version

In my case is Debian 10.2.1-6 = "buster".

2. Install the repository's GPG key:

curl https://pkg.cloudflareclient.com/pubkey.gpg | sudo apt-key add -

3. Add and update repository

There you need to check your version of Debian relesae name. The name should be in lower case.

echo 'deb http://pkg.cloudflareclient.com/ buster main' | sudo tee /etc/apt/sources.list.d/cloudflare-client.list

sudo apt update

4. Install WARP

sudo apt install cloudflare-warp

Finaly, we can use WARP.
