How to upgrade a Livepatch on-prem deployment

Project Discussion Livepatch
1

To upgrade the livepatch on-prem deployment, each application needs to be upgraded separately:

$ juju refresh haproxy

$ juju refresh postgresql

$ juju refresh ubuntu-advantage

$ juju refresh livepatch

After upgrading the livepatch application, a schema upgrade may be required. This will be indicated in the application’s status in juju status. In such a case, run the command:

$ juju run-action livepatch/leader schema-upgrade --wait

One can also restart the livepatch application with the following command:

$ juju run-action livepatch/<desired-unit> restart --wait

Note: juju run-action has been renamed to juju run from Juju v3
See Juju | How to manage actions for more details.
