Update to Debian 11 - Grafana Stops working

Hello

I am running on a virtual machine (LXC) under proxmox a debian buster with grafana and influxdb.

As i want update influxdb i have to first update debian to bullseye.

So first i update debian with this instruction to debian 11

sudo apt full-upgrade
sudo apt autoremove
sudo sed -i 's/buster/bullseye/g' /etc/apt/sources.list
sudo sed -i 's/buster/bullseye/g' /etc/apt/sources.list.d/*.list
sudo sed -i 's#/debian-security bullseye/updates# bullseye-security#g' /etc/apt/sources.list
export LC_ALL=C 
sudo apt update
sudo apt upgrade
sudo apt full-upgrade
sudo apt autoremove
sudo systemctl reboot

but after this i cant start grafana anymore - i tried to uninstall install it, also to uninstall before updating then installing it… now chance, and looks like this:

root@datenTest:~# sudo systemctl status grafana-server
* grafana-server.service - Grafana instance
