Meanwhile I have added the openssl dependency to the rpm. I am not sure that this will solve your issue, because it is likely that openssl is already present anyway.

If the problem persists, try if you can execute /usr/lib/unifi/bin/import-cert as root. Your key and certificate must be readable by root only. Access from user and group unifi is not necessary. The key must be accessible without a password, to be copied in Javas password store.

Hello, I did a new clean installation. There is no user unifi in /etc/passwd nor a unifi group in /etc/groups. I started import-cert as root: ./import-cert: No certifcate and/or key specified leave Ubiquities certificate. I do not need a own cert.

Looks like the creation of user and group "unifi" ist still broken. I will setup a virtual machine to test and fix initial installation of the package.

Now everything works fine. Thanks a lot :)
