The following bug has been logged on the website: Bug reference: 15845 Logged by: jr Email address: (redacted) PostgreSQL version: 11.0 Operating system: Fedora 29 Description: The repo I use for Fedora 29 is : https://download.postgresql.org/pub/repos/yum/11/fedora/fedora-29-x86_64/ and the directory repodata is missing in that repo : thus the installation cannot be performed because dnf claims that the repo cannot be cached. (for information : the equivalent for Fedora28 and Fedora30 are ok)
