Lab stuck after press "setup" button

[chesswithpidgeon]

Hello everybody,

trying to install the lab, i notice a lot of error.

Apparently randomly, 3 errors occur:

• DISPLAY environment variable
• err98: address already in use
  -the one of the image. The setup process of the lab is stuck, and the following is the code snippet that i see in terminal:

Could you please help me?

Thank you

hi, i won't give you a real solution, but when it happens to me that i got stuck after pressing setup cause my docker service doesn't start i first check the service status sudo systemctl status docker.service than i force the start sudo systemctl start docker.
than you can also do systemctl enable docker to start it from the next reboot.
hope it helps a little
