Examples
Set the base for the ubuntu application to ubuntu@20.04:
juju set-application-base ubuntu ubuntu@20.04
Details
The specified application’s base value will be set within juju. Any subordinates of the application will also have their base set to the provided value. A base can be specified using the OS name and the version of the OS, separated by @.
This will not change the base of any existing units, rather new units will use the new base when deployed.
It is recommended to only do this after upgrade-machine has been run for machine containing all existing units of the application.
To ensure correct binaries, run ‘juju refresh’ before running ‘juju add-unit’.
