Official install not working for Ubuntu 24.04 LTS

Sensu Go Getting Started
1

I’ve always used Ansible to set up an APT/DEB repo to pull sensu go agents from, but the snippet below no longer works. At Sensu | Sensu Go Downloads the “latest” support distro/packaging is Focal. Any plans on creating releases for the 24.04 LTS?

    - name: Install Sensu packages repository
      apt_repository:
        repo: "deb https://packagecloud.io/sensu/stable/ubuntu/ {{ ansible_distribution_release }} main"
        state: present
        filename: sensu-stable

    - name: Install Sensu Ruby Plugins repository
      apt_repository:
        repo: "deb https://packagecloud.io/sensu/community/ubuntu/ {{ ansible_distribution_release }} main"
        state: present
        filename: sensu-community

I see this was kind of reported here too: Unable to locate the package sensu-go-backend - #2 by JustinToo

The official install method of using the scripted solution from packagecloud also results in the same failed install:

# Add the Sensu repository
curl -s https://packagecloud.io/install/repositories/sensu/stable/script.deb.sh | sudo bash

# Install the sensu-go-agent package
sudo apt-get install sensu-go-agent

example:

root@machine345:~# curl -s https://packagecloud.io/install/repositories/sensu/stable/script.deb.sh | sudo bash

I wasn’t aware of the cutting of resources/funding …

It’s now coming up on 4 months that I did the “still alive” post and except that post by Justin, not a lot happened…

I still like sensu go and don’t really want to look for something else, maybe we need a fork?

As a hacky workaround, try replacing noble with jammy in the APT sources file.

For ansible:

pre_tasks:
    - set_fact:
        ansible_distribution_release: "jammy"
      delegate_to: "{{ item }}"
      with_items: "{{ play_hosts }}"
      run_once: yes
      when: ansible_distribution_release == "noble"

Hey @ceda, :wave:

To answer your initial quesiton, our last release 6.11.0 was just prior to Ubuntu 24.04 (Noble Numbat), so packages for it do not yet exist. We will release 24.04 packages with Sensu Go 6.12.0, our next minor release, which is planned for this month, or next.

I can validate @teutat3s method, I use it when I’m testing on newer, or unsupported OS’s.

Here’s the hacky workaround if you’re not using ansible and just installing it manually.

Manually add the repository for jammy:

echo "deb https://packagecloud.io/sensu/stable/ubuntu/ jammy main" | sudo tee /etc/apt/sources.list.d/sensu.list

If the directory /etc/apt/keyrings does not already exist, create it:

sudo mkdir -p /etc/apt/keyrings

Download and add the Sensu GPG key:

curl -fsSL https://packagecloud.io/sensu/stable/gpgkey | sudo gpg --dearmor -o /etc/apt/keyrings/sensu.gpg

Create a file to configure the GPG key:

echo "deb [signed-by=/etc/apt/keyrings/sensu.gpg] https://packagecloud.io/sensu/stable/ubuntu/ jammy main" | sudo tee /etc/apt/sources.list.d/sensu.list

Update your package lists:

sudo apt-get update -y

Now try to install Sensu:

sudo apt-get install -y sensu-go-agent

That was in July, so “this month or next” is over… #sad

Based on commits in this branch from two days ago, it appears a bug fix 6.11.1 release is in the pipeline to address this issue.

We know there’s been promises for 6.12.0 to include Ubuntu 24.04 packages, and updated Docker images. I would hope there would also be packages for RHEL 9 as well. I’m not sure what else to expect as the 6.11.0 release was only a bump in some package dependencies in a change to the FIPS build.
