Unable to download Falco in Kali Linux

Question

I am trying to install Falco in Kali Linux. The official download documentation can be found here.

When I try and execute the command

apt-get update -y

I am getting following error.

E: The repository 'https://download.docker.com/linux/debian kali-rolling Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

Also when I run the command :

apt-get install -y falco

I get the following error:

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package falco

I tried updating the entire OS and even installed Linux headers still the same. I tried doing it as a root user and as a new user too. The errors are the same. How to install Falco in Kali Linux?

Answer 1

You have tow error:

1). The first one come from docker-ce repository, because docker-ce doesn't support kali-rolling codename, to correct the problem use the following command:

sudo rm -rf /etc/apt/sources.list.d/*

Then install it properly: Installing Docker on Kali Linux

printf "%s\n" "deb [arch=amd64] https://download.docker.com/linux/debian buster stable" \
| sudo tee /etc/apt/sources.list.d/docker-ce.list

curl -fsSL https://download.docker.com/linux/debian/gpg \
| sudo apt-key add -

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io

2). The second error message come from flaco repository.

To install flaco use the Linux generic (binary package) method :

curl -L -O https://dl.bintray.com/falcosecurity/bin/x86_64/falco-0.27.0-x86_64.tar.gz
tar -xvf falco-0.27.0-x86_64.tar.gz
cp -R falco-0.27.0-x86_64/* /
echo "alias flaco='falco-0.27.0-x86_64/usr/bin/falco'" >> ~/.bashrc
source ~/.bashrc
