No http web frontent when using "debian_bullseye_server_linux6.1.31"

Hi,
after I have successfully installed Hyperion on "debian_bullseye_desktop_xfce_linux6.1.31" , I tried to install it on "debian_bullseye_server_linux6.1.31".

Unfortunately, I can´t reach the http web frontend at port 8090/8091 on server version .
I am a newbie in Linux and can´t find any tutorial how to find and install the missing service.
Hope that someone can help.

Hi pclin #2,
thank you for your reply.

Maybe I did something/explained wrong.

hypersion service is starting automatically I think.
After command: service hyperion@root status
I get:
● hyperion@root.service - Hyperion ambient light systemd service for user root

Loaded: loaded (/etc/systemd/system/hyperion@.service; enabled; vendor preset: enabled)

Active: activating (auto-restart) (Result: exit-code) since Sun 2024-02-11 12:15:27 CET; 1s ago

Docs: https://docs.hyperion-project.org

Process: 2147 ExecStart=/usr/bin/hyperiond (code=exited, status=127)

Main PID: 2147 (code=exited, status=127)

CPU: 8ms

I followed your advice and added the directory: .config/autostart

the file: hyperion.desktop

with conten:

[Desktop Entry]

Type=Application

Name=hyperion

Exec=hyperion

StartupNotify=false

Terminal=true

command: chmod +x hyperion.desktop

Unfotunately, I still can´t reach hyperion under IP:8090/8091

What did I wrong?

"apt-get install libpython3.9" did the job finally

Thanks pclin
