Cannot start docker on lubuntu - "cannot start container: exec format error"

Question

I ran sudo apt-get install docker.io in my lubuntu 14.10, but it says cannot start container when I run this:

sudo docker run ubuntu echo "Hello World"

exec format error2015/03/16 16:31:16 Error response from daemon: Cannot start container ad265ac9c2635f42e4244472d181a2121ecba4d855fa33c10599d91aa932d2cd: exec format error

Can not find out the answer, guest it maybe related with the lubuntu.

The container is created, but why do I only got the "exec format error"

sudo docker ps -a

Answer 1

You're running a 32-bit host, which is largely unsupported by Docker. You definitely won't be able to run 64 bit images such as the stock ubuntu.

There are however some 32-bit images you can try, e.g: https://registry.hub.docker.com/u/32bit/debian/

You can find some more information here https://github.com/docker/docker/issues/7513
