Docker Upgrade from v1.11 to v1.12 using apt-get on Ubuntu 14.04.4 LTS
sudo apt-get upgrade docker-engine
For some unknown reasons this will result in fetching and unpacking almost every package and library in my linux ( linux-images, lightdm, jvm,etc.). This has been going on for an hour now.
Does anyone have any idea what is going wrong and how it can be stopped without messing up my Ubuntu installation?
( in case you are planning to upgrade your docker using this, just don’t. a purge an reinstall is a much better choice if you like your Ubuntu)

apt-get upgrade always upgrades all the packages on your machine.
$ apt-get update && apt-get install docker-engine -y
