Introduction

This guide outlines the necessary steps for migrating to an Ubuntu Pro on Premise instance.

...

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. The following configuration lines should be removed in Run the command below if the file still exists /etc/apt/auth.conf.d/90ubuntu-advantage

   Code Block
   machine esm.ubuntu.com/apps/ login bearer password ... # ubuntu-advantage-tools machine esm.ubuntu.com/infra/ login bearer password ... # ubuntu-advantage-tools

3. Remove virtual machine from the Landscape server

...

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

2. 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: http://vss-ubuntu-pro.eis.utoronto.ca:8484$(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 [TOKEN] $(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.token")

   output:

   Code Block

   Edit the following path: /etc/apt/auth.conf.d/90ubuntu-advantage and add “http://”

   Code Block
   machine http://vss-ubuntu-pro.eis.utoronto.ca/esm-apps/ubuntu/ login bearer password ... # ubuntu-pro-client machine http://vss-ubuntu-pro.eis.utoronto.ca/esm-infra/ubuntu/ login bearer password ... # ubuntu-pro-client

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. Add the virtual machine to the landscape server. Login into the Landscape Server to get the Registration Key.(optional) If you are running landscape-client, proceed with the following command, otherwise skip

   Code Block
   sudo landscape-config --computer-title "[Server Name]"pro enable landscape --account-name standalone -p [REGISTRATION_KEY] --url https://vss-ls.dcb.eis.utoronto.ca/message-system --ping-url http://vss-ls.dcb.eis.utoronto.ca/pingassume-yes

   output:

   Code Block

   enabled This script will interactively set up the Landscape client. It will ask you a few questions about this computer and your Landscape account, and will submit that information to the Landscape server. After this computer is registered it will need to be approved by an account administrator on the pending computers page. Please see https://landscape.canonical.com for more information. The Landscape client communicates with the server over HTTP and HTTPS. If your network requires you to use a proxy to access HTTP and/or HTTPS web sites, please provide the address of these proxies now. If you don't use a proxy, leave these fields empty. HTTP proxy URL: HTTPS proxy URL: Landscape has a feature which enables administrators to run arbitrary scripts on machines under their control. By default this feature is disabled in the client, disallowing any arbitrary script execution. If enabled, the set of users that scripts may run as is also configurable. Enable script execution? [Y/n]: By default, scripts are restricted to the 'landscape' and 'nobody' users. Please enter a comma-delimited list of users that scripts will be restricted to. To allow scripts to be run by any user, enter "ALL". Script users [landscape]: You may provide an access group for this computer e.g. webservers. Access group: You may provide tags for this computer e.g. server,precise. Tags [development,database]: Please wait... Request a new registration for this computer now? [y/N]: y System successfully registered.

1. 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="http://vss-ubuntu-pro.eis.utoronto.ca:8080/"$(vmware-rpctool "info-get guestinfo.ut.vss.ubuntu_pro.livepatch.endpoint")

3. Verify configuration

   Code Block
   canonical-livepatch config

   output:

   Code Block
   root@backup-billing-db-dev:/home/oramirez# canonical-livepatch config http-proxy: "" https-proxy: "" no-proxy: "" remote-server: http://vss-ubuntu-prolivepatch.eis.utoronto.ca:8080/ 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 <TOKEN_ON_VSS>$(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

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

   Code Block
   systemctl restart landscape-client
