I don't know what happened but my work is completely paralyzed. I can't do anything with existing containers. I get

Error response from daemon: 404 page not found

error on pretty much all commands.

I googled a lot and some people recommended adding

export NO_PROXY="/var/run/docker.sock

line to /etc/default/docker. It fixed "docker info" command but not the rest such as rm, start or restart.

I have:

I tried reinstalling docker which also didn't fix it.

It seems like it's an issue with proxy setting and is some obvious bug. If I call unset http_proxy before running docker command it helps. With that I can remove container and recreate it again thus launching it. But doing so on every reboot is horrible.

Please help!!!
