Has anyone had luck installing on debian 13? They appear to have changed a handful of the packages and attempting to spin up a new debian 13 based system yields some issues finding an appropriate java install.

Code: Select all

Welcome to the Unimus installer!

This installer will perform the following steps:
1) Install a compatible Java version (if not already present)
2) Install dependencies [curl haveged procps apt-transport-https] (if not already present)
3) Install the latest version of Unimus
4) Configure Unimus to start at boot
5) Start Unimus

If you are upgrading from a previous version, your current Unimus service will be stopped and restarted automatically.

If you experience any issues with this installer, or have any questions, please contact us.
(email, website live-chat, forums, create a support ticket, etc.)

Press ENTER to continue, or Ctrl+C to exit:

Updating list of available packages, this might take a while...
(running 'apt-get update' to refresh package indexes)


Package dependencies installed, continuing...

Checking if supported Java installed...
Supported Java version not found, will install Java...

ERROR: It seems none of the supported Java packages were found.

This usually happens when you try to run the installer on an unsupported OS.
You can try to install Java 8 or newer manually and restart this installer.

Alternatively, please contact us so we can add support for your OS.

Answered my own question:
To install unimus on Debian 13 you must first manually install the openjdk and openjre.

Code: Select all

apt-get install -y default-jre default-jdk
the install will then complete as expected.
