What you need
Ubuntu 24.04 amd64, sudo privileges, curl, GnuPG and access to the official APT repository.
Procedure
- Download the public repository key. Check the primary fingerprint 0D92 778A D8EC F85C 80E3 9248 48F2 433A D9CD F453 against an independently trusted copy before installing it.
- Install the key under /etc/apt/keyrings and create /etc/apt/sources.list.d/ch-j.sources using the example. Signed-By limits this key to the repository.
- Run sudo apt update and sudo apt install ch-j-server-manager. On first launch, review the application operational guidance and license terms.
- Use APT for later repository updates. Do not run the separate application installer during an APT transaction.

Limitations and checking results
The package currently uses the Alpha channel and amd64 architecture. Compatibility with every Debian version or other architectures is not guaranteed.
Do not use apt-key, disable signature checking or trust the key globally. License consent takes place in the application; website downloads begin directly.
An Alpha development version is available. Before using it on important systems, review the limitations of individual features and prepare backups.
