Lemur init dont work von Ubuntu 22.04

[Chiller2019]

Hey, I follow the Quickstart-Guide from: https://lemur.readthedocs.io/en/latest/quickstart/index.html

My System:
Ubuntu 22.04 LTS (Fresh installation on proxmox as LXC with nesting and keyctl + unprivileged container)
Python3: 3.10.6
Node: 12.22.9
postgresql: 14.8

Installted packages: nodejs npm python3-pip python3-dev libpq-dev build-essential libssl-dev libffi-dev libsasl2-dev libldap2-dev nginx git supervisor postgresql <- not python-dev and python-pip (because outdated -> python3-dev and python3-pip installed)

But it stucks on lemur init with the following error:

(lemur) lemur@Lemur:/www/lemur/lemur$ lemur init

Any suggestions?

Tried LXC with Ubuntu 22.04/20.10 and 22.04 as VM.
All LXC/VMs fail at the same command.
