Introduction

This guide outlines the necessary steps for migrating to an Ubuntu Pro On-Premise (VSS CGN) instance from an existing Ubuntu Pro subscription, ensuring a seamless transition.

Current Active Services

Pre-requisites

1. To ensure smooth operation, please detach any previously connected virtual machines from Ubuntu Pro. Execute the following commands with administrative privileges:

   Code Block
   pro detach

   output:

   Code Block
   Detach will disable the following services: esm-apps esm-infra landscape livepatch Are you sure? (y/N) y Updating package lists Updating package lists Executing `landscape-config --disable` /etc/landscape/client.conf contains your landscape-client configuration. To re-enable Landscape with the same configuration, run: sudo pro enable landscape --assume-yes

2. Run the command below if the file still exists /etc/apt/auth.conf.d/90ubuntu-advantage

   Code Block
   echo "" > /etc/apt/auth.conf.d/90ubuntu-advantage

3. Run the following command through the vss-cli to present the latest endpoint settings

   Code Block
   vss-cli compute vm set {id} ubuntu-pro attach

...

Ubuntu Pro

1. Configure the Ubuntu Pro Client by editing the contract_url setting in /etc/ubuntu-advantage/uaclient.conf to point to the server:

   Code Block
   echo "contract_url: $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.endpoint")" > /etc/ubuntu-advantage/uaclient.conf

2. Check everything works fine with the following command:

   Code Block
   pro refresh

   output:

   Code Block
   Successfully processed your pro configuration. This machine is not attached to an Ubuntu Pro subscription. See https://ubuntu.com/pro

3. Attach your token:

   Code Block
   pro attach $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.token")

   output:

   Code Block

4. Update the Ubuntu repositories and ensure there are no errors related to the vss-ubuntu-pro repositories:

   Code Block
   apt-get update

   output:

   Code Block

   Hit:1 http://vss-ubuntu-pro.eis.utoronto.ca/esm-apps/ubuntu focal-apps-security InRelease Hit:2 http://vss-ubuntu-pro.eis.utoronto.ca/esm-apps/ubuntu focal-apps-updates InRelease Hit:3 http://vss-ubuntu-pro.eis.utoronto.ca/esm-infra/ubuntu focal-infra-security InRelease Hit:4 http://vss-ubuntu-pro.eis.utoronto.ca/esm-infra/ubuntu focal-infra-updates InRelease Hit:5 http://ca.archive.ubuntu.com/ubuntu focal InRelease Hit:6 http://ca.archive.ubuntu.com/ubuntu focal-updates InRelease Hit:7 http://ca.archive.ubuntu.com/ubuntu focal-backports InRelease Hit:8 http://ca.archive.ubuntu.com/ubuntu focal-security InRelease Reading package lists... Done

5. (optional) If you are running landscape-client, proceed with the following command, otherwise skip

   Code Block
   sudo pro enable landscape --assume-yes

   output:

   Code Block
   One moment, checking your subscription first Landscape is not available for Ubuntu 22.04 LTS (Jammy Jellyfish).

LivePatch

...

1. Install the following packages in the client

   Code Block
   sudo snap install canonical-livepatch

2. Configure the on-prem server

   Code Block
   canonical-livepatch config remote-server=$(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.livepatch.endpoint")

3. Verify configuration

   Code Block
   canonical-livepatch config

   output:

   Code Block
   http-proxy: "" https-proxy: "" no-proxy: "" remote-server: http://vss-ubuntu-livepatch.eis.utoronto.ca/ ca-certs: "" check-interval: 60 # minutes log-level: WARNING disable-signature-verification: false tls-patch-download: false

4. Enable the Livepatch updates with the token

   Code Block
   canonical-livepatch enable $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.livepatch.token")

   output:

   Code Block
   Successfully enabled device. Using machine-token: <RANDOM_NUMBERS_OF_TOKEN>

5. Check status of Ubuntu Pro

   Code Block
   pro status

   output:

   Code Block

   SERVICE ENTITLED STATUS DESCRIPTION anbox-cloud yes disabled Scalable Android in the cloud esm-apps yes enabled Expanded Security Maintenance for Applications esm-infra yes enabled Expanded Security Maintenance for Infrastructure fips yes disabled NIST-certified FIPS crypto packages fips-updates yes disabled FIPS compliant crypto packages with stable security updates livepatch yes enabled Canonical Livepatch service ros yes disabled Security Updates for the Robot Operating System usg yes disabled Security compliance and audit tools For a list of all Ubuntu Pro services, run 'pro status --all' Enable services with: pro enable <service> Account: University of Toronto - EIS Private Cloud Subscription: Ubuntu Pro Valid until: Sat Jun 22 19:59:59 2024 EDT Technical support level: essential

6. (Optional) If you are running Landscape, proceed to restart landscape-client, otherwise skip this step.

   Code Block
   systemctl restart landscape-client
