I know it's a cliche question, but have you tried to restart the vm and see if it will fix the issue? If you have tried this, have you tried to remove the package, restart the vm - then install the package again? If possible, just decomission the vm entirely, and get a new one, and try the same installation steps from scratch.
Do you have any other software running on the same vm? I don't mean standard services that come with your distro, but something you deliberately added, except Gluu Server.
Also, could you share your `setup.properties.last` file? Its location: `/install/community-edition-setup/setup.properties.last.enc` By default it's encrypted, so you'll need to run this to decrypt it before sharing: `# openssl enc -d -aes-256-cbc -in setup.properties.last.enc -out setup.properties.last` Use any file sharing service you wish, or just mail it to `email@example.com`
