How to uninstall docker-engine?

Question

I have installed the docker with

curl -sSL https://get.docker.com/ | sh

When I tried to uninstall the package, I am facing the following error

$ sudo apt-get remove docker-engine

How am I to uninstall the docker package?

I am using Ubuntu 15.04.

Answer 1

Try it

sudo mv /var/lib/dpkg/info/{packagename}.* /tmp/
sudo dpkg --remove --force-remove-reinstreq {packagename}
sudo apt-get remove {packagename}
sudo apt-get autoremove && sudo apt-get autoclean

Answer 2

I had the same problem but in Ubuntu 14.04. The way that I resolve this problem was:

First remove bad links:

sudo mv /var/lib/dpkg/info/{packagename}.* /tmp/
sudo apt-get remove {packagename}

So now you can install it again:

sudo apt-get install docker-engine

Thats all.
