Wazuh Agent installation on Linux

[tsurara36]

Hi all,
I am new to Wazuh and am now trying to install an Agent on my Linux operating system. I have followed the guide to installing the agent, where i typed:
curl -s https://packages.wazuh.com/key/GPG-KEY-WAZUH | gpg --no-default-keyring --keyring gnupg-ring:/usr/share/keyrings/wazuh.gpg --import && chmod 644 /usr/share/keyrings/wazuh.gpg
and it gave me

After that I input
echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | tee -a /etc/apt/sources.list.d/wazuh.list
and it gave me

Finally i input
apt-get update
and it gave me


What should I do to resolve this issue?

Hi @tsurara36,

It seems like you have both the 3.x and the 4.x repositories on your endpoint, remove the old one to avoid conflicts.

For example, in the second command, you can remove the append -a option to overwrite the file:

echo "deb [signed-by=/usr/share/keyrings/wazuh.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | tee /etc/apt/sources.list.d/wazuh.list

Also, make sure to remove old Wazuh agents that might be present. See the uninstalling a Wazuh agent instructions to learn more.

As an alternative to this installation method, you can follow the instructions in your Wazuh dashboard under Agents > Deploy new agent. Select your operating system and architecture, set your Wazuh manager address and use the resulting command to download, install and enroll your agent. For example:

curl -so wazuh-agent.deb https://packages.wazuh.com/4.x/apt/pool/main/w/wazuh-agent/wazuh-agent_4.4.1-1_amd64.deb && sudo WAZUH_MANAGER='10.0.0.2' dpkg -i ./wazuh-agent.deb
