Runing automata net on frsh Ubuntu 21.04

[adamvm]

Hi, I conduct build process according to instaction
I have installed docker and docker-compose

I have this problem:

a@s:~/progs/automata$ sudo ./scripts/run-network.sh
[sudo] hasło użytkownika adi: 
Running the network
Image: automata
Chain: local
Pulling validator-a (automata:)...
ERROR: The image for the service you're trying to recreate has been removed. If you continue, volume data could be lost. Consider backing up your data before continuing.

Continue with the new image? [yN]y
Pulling validator-a (automata:)...

ERROR: Couldn't connect to Docker daemon at http+docker://localhost - is it running?

If it's at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

How I can make automata running?
