I installed the Docker version of Alfresco and all the services start correctly.
Starting activemq ... done
Starting solr6 ... done
Starting share ... done
Starting alfresco ... done
Starting postgres ... done
But none of the URLs can be launched.
The browser just waits for the completion ogf the operation and the anti clockwise circle at the browser tab keeps on turning anticlockwise indefinitely. I tested for more than 45 minutes and still the operation didnt complete.
