I am trying to delete freshly created package, but error code says delete is not a valid command.
But it’s available in official document
You will need to use prerelease version of the Salesforce CLI
You can install using the command below
sfdx plugins:install salesforcedx@pre-release
The functionality will be available once winter 21 v50.0 is generally available!
Also this will only work with the DevHub in prerelease orgs for now.
