There is now a new Directus 9 package which obsoletes the old Directus 8 package. Directus 8 is hidden in the appstore but still available under the id
io.directus.cloudronapp(set the id in the browser URL bar to install).
There is no automated migration from Directus 8 to 9 since things have changed drastically. See https://docs.directus.io/configuration/upgrades-migrations/#manual-database-export-import for instructions.
App Library: https://www.cloudron.io/store/io.directus9.cloudronapp.html
Package Repo: https://git.cloudron.io/cloudron/directus-app (same as before!) The old repo was moved to https://git.cloudron.io/cloudron/directus8-app
