I tried to install Eaton Intelligent Power Protector onto a Proxmox 6.5.11-8 machine (based on 12.5 Debian without desktop environment).

Installation failed as the installer could not install the proper user for running the process of the software.

The required UIDs and GID are 998/998. I found that out when I installed the Software onto another Debian 12.5 machine with Xfce. There everything works fine.

When I try to add the user manually, I get the error code from above User ID 998 is not unique/already in use. That seems to be the reason why the installer was not capable of adding it. But I don’t find any traces of this user ID on the system ..

Does anybody have a clue why it is possible to create the user on 12.5 with Xfce but not on the Proxmox machine? Running the process with this user having a different ID does not work. Running it with root does fine but of course we don’t want that.

Thanks!
