Blank screen after filling the setup form in version 10.6

[cruftex]

I did the following

1. git clone https://github.com/resourcespace/docker.git resourcespace
2. docker compose up --build -d
3. wait around 5 minutes
4. connect to localhost:80
5. fill the setup form, with database user and password and provide some email addresses to use
6. press begin installtion

I get a blank screen just with the resourcespace logo:

No hint in the logs:

docker compose logs resourcespace -n 100

resourcespace  |  * Starting periodic command scheduler cron
resourcespace  |    ...done.
resourcespace  | AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 172.23.0.3. Set the 'ServerName' directive globally to suppress this message

Note:
It would be good to get rid of the setup from altogether. In the docker the database coordinates and other configs should come from environment variables.

Also ran into this issue when following the instructions here. Same log message from docker, but the page includes this line of text: Error opening output file. (This should never happen, we should have caught this before we got here)

Logs: $ docker logs -t 50

#10 described a fix that worked for me.
The only thing I had to fix was issue 1 which was basically this command to fix the permission issue:

docker exec -it resourcespace bash -c "chmod 666 /var/www/html/include/config.php"
