pgadmin4 service won't start

I am not a sysadmin but since I can't afford paying one, I need to do the job myself ;-) I have a lxc container running on a proxmox4 box. proxmox4$ uname -a Linux dbd 4.4.98-2-pve #1 SMP PVE 4.4.98-101 (Mon, 18 Dec 2017 13:36:02 +0100) x86_64 GNU/Linux In the container, I installed PGAdmin4 as a service. Installation is in my home directory. I also installed systemd as it wasn't there by default. I created a /lib/systemd/system/pgadmin4.service. PGAdmin won't start and here is the output of : $ sudo systemctl -l status pgadmin4 pgadmin4.service - Pgadmin4 Service Loaded: loaded (/lib/systemd/system/pgadmin4.service; enabled) Active: failed (Result: exit-code) since Tue 2018-01-30 13:35:49 UTC; 9s ago Process: 673 ExecStart=/home/ballama/pgadmin/lib/python2.7/site-packages/pgadmin4/pgAdmin4.py (code=exited, status=226/NAMESPACE) Main PID: 673 (code=exited, status=226/NAMESPACE) Jan 30 13:35:49 dbd systemd: Started Pgadmin4 Service.

I am stuck and do not know how to solve this. Any help appreciated of course. Marc
