Grafana/log-analyser not working after fresh setup with docker on Ubuntu24

[pzystorm]

Hi,
to install I have followed these instructions: https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-log-analyser/

My system:

# docker -v
Docker version 27.3.1, build ce12230
# docker compose version
Docker Compose version v2.29.7
# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.1 LTS
Release:        24.04
Codename:       noble

After starting I first had the problem, that Grafana complained about not having permissions to write to /var/lib/grafana. But after chmod -R a+w log-analyser this problem is gone. I have realized that grafana is not runnning under root in the docker container but rather under a local user with the id 472.

Now it starts, but after doing a lot of migration and import stuff with the output of "Migration successfully executed" it stated, that there is some error with the admin user and some dashboards and a database lock:

Do you have any ideas on that? Is it a bug or version incompability or am I doing something wrong?
