Hi @makkipasha, We implement latest version of Ubuntu in upcoming releases, but if you need ti start cluster on Ubuntu 24.04 now please following instruction from READ.me but with some changes:

1. Do not install python 3.9, we will use 3.12 which installed by default, so on “Docker and k8s installation” step from manual perform commands: sudo apt update → sudo apt install python3-pip sshpass git python3-virtualenv And create virtual env using command: virtualenv -p python3 venv

2. Before installing requirements need to change ansible version to 9.0.0 in file /optscale-deploy/requirements.txt and then execute commands: source venv/bin/activate → pip install -r requirements.tx

3. Before you start ansible-playbook need to change: 3.1. docker and k8s versions in file: **optscale-deploy/ansible/roles/common/defaults/main.yaml. Please use required_docker_version: "26.0" and kubernetes_version: 1.21.14 3.2 pip version to 24.0.0 in file optscale-deploy/ansible/roles/common/tasks/optscale-tools.yaml in Upgrade pip step 3.3 Need to update rabbitmq template optscale-deploy/optscale/templates/rabbitmq.yaml Need to change “localhost” to “127.0.0.1” in 2 strings with command: wget -O - -q --header "Authorization: Basic echo -n "$RABBIT_MANAGEMENT_USER:$RABBIT_MANAGEMENT_PASSWORD" | base64" http://localhost:15672/api/healthchecks/node | grep -qF "{\"status\":\"ok\"}"

After that we need to create config file for docker. Create folder using command sudo mkdir -p /etc/systemd/system/docker.service.d/ and config file sudo touch /etc/systemd/system/docker.service.d/deprecated_manifest.conf. Open file and add environment variable:

[Service]
Environment ="DOCKER_ENABLE_DEPRECATED_PULL_SCHEMA_1_IMAGE=1"

After that start ansible playbook and runkube as described in READ.me
