but I get a “The repository “https://apt.releases.hashicorp.com ulyssa Release” does not contain a release file” (translated from my german message) in the last step.
Which says ‘The Debian and RPM packages currently target popular x86_64/amd64 systemd systems. The repository supports many versions of Debian, Ubuntu, Fedora, CentOS, RHEL, and AmazonLinux. If your platform is not in this list but your system is compatible with Debian or RPM packages, you can still add the repository by specifying a supported release name for apt or $releasever for yum or dnf when you add the repository. This support will expand to other architectures and platforms in the future.’ I do not know how to modify the script to specify a release version, nor do I know what I can / should put in?
