teamviewer-host headless in Debian 12 setup

TL3

Hello,

i am trying to use teamviewer-host on an embedded headless Linux device running Debian 12 (Buster).

I am connected via SSH (root user) and installed the TV-host v15.20.6 deb package.

The daemon status is up and running, but executing "teamviewer setup" results in the error:

TeamViewer daemon is not running, setup cannot continue. Please activate the TeamViewer daemon before invoking setup.

I found that this issue has been raised a couple times, but always without a solution.

TL3

by accident i found that i had to enable the "systemd-logind" service (this one was masked on my device)

Now i can procceed in the setup command but already got stuck in the next issue:
