I tried to update the docker as suggested in his guide
sudo apt-get upgrade docker-engine
For unknown reasons, this will lead to the extraction and unpacking of almost every package and library in my Linux (linux-images, lightdm, jvm, etc.). This has been going on for an hour.
Does anyone know what is going wrong and how can I stop it without starting my Ubuntu installation?
(in case you plan to upgrade your docker using this, just don't do it. cleaning reinstallation is a much better choice if you like your Ubuntu)
