The Solution

If you are using “dnf config-manager –add-repo” to add a repository, the command does not add the GPG key file location configuration for that repository. A package installation would fail, as by default, dnf enables gpgcheck. It equires the GPG key to be set or imported.

1. Manually set and import the GPG key file location:

# rpm --import "file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle"

or

2. Add or set the GPG key for all of the individual repository entries under /etc/yum.repos.d:

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
