Installation problem: yaml.scanner.Scanner Error

[wobblebobble]

Hi,
Tried to install today, but I got the following error:

U20LTS:/usr/local/IoT_Data_Simulator$ docker-compose pull
ERROR: yaml.scanner.ScannerError: mapping values are not allowed here
  in "./docker-compose.yml", line 92, column 65

As I am not a programmer, I don't know what to do here.
Can you help?
thank you!!

Update: It seems that the problem was that I only downloaded the two release files and not the whole git content.
So I did and the installation started.
Nevertheless I have an new problem, several connection refused messages during installation process.
A colleague of mine tested it on his VM with Ubuntu 20 and it worked. He also tried on my VM, but failed. So, I don't know, maybe the cause is somewhere else. We gave up at this point.
