Hi

I invested a lot of time, trying to generate a valid 2GP package and install it to a newly created Scratch Org without any success.

Do you have some tips which flows i should use?

I tried release_2gp_beta but i get always an error when i install the package in a Scratch Org created over CumulusCI (with cci org scratch dev dev-test and then cci flow run dependencies --org dev-test to install npsp). First i had issues with a ConnectedApp then i had a general error message like in the attachment.

Have i missed something?

And one more thing i don't understand: when i have a release-tag in github-repo, the release_2gp_beta fails with the error:

Response content: [{'message': 'Can’t create the package version. The ancestor package version specified in the sfdx-project.json file hasn’t been promoted and released. Release the ancestor package version before specifying it as the ancestor in a new package or patch version.', 'errorCode': 'INVALID_INPUT', 'fields': []}]

Run this command for more information about debugging errors: cci error --help

Do you have some informations about this error?
