    Check user is enrolled, and set a query URL in the network
    Make query
    Assigning transaction_id:  f7d1d9b40c37bb21909bdb6ff24980da33758fb1ea5a85cb67d699f3fcd3ffa2

It seems like the problem is caused due to Docker version.. Try the following codes, it should solve the issue..

sudo apt-get --purge remove docker-ce
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
sudo apt-get update
apt-cache policy docker-ce
sudo apt-get install -y docker-ce
