The customer is trying to publish his Java package to the Maven Central Repository and GitHub Packages in a GitHub Actions workflow. He is authenticating with the GPG key to publish the package.
He refers to the examples mentioned in "Publishing Java packages with Maven" and the README of the setup-java action to setup the workflow.
But he gets the following errors:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-gpg-plugin:1.6:sign (sign-artifacts) on project ***: Unable to decrypt gpg passphrase: org.sonatype.plexus.components.sec.dispatcher.SecDispatcherException: java.io.FileNotFoundException: /home/runner/.m2/settings-security.xml (No such file or directory) -> [Help 1]

OR

gpg: signing failed: Inappropriate ioctl for device
