dockerfile - Getting an "operation not supported" error when trying to RUN something while building a docker image -


i'm trying build docker image following command:

docker build -f conf/dockerfile -t my_app_name .

the dockerfile starts with:

from ubuntu:14.04  copy conf/pubkey pubkey run echo 'deb http://downloads.skewed.de/apt/trusty trusty universe' >> /etc/apt/sources.list \   && apt-key add pubkey \   && rm pubkey

and returns info[0000] operation not supported.

regardless of put after run (even run echo 1 fails)

i tried running shell in intermediate docker image (docker run a7bb092… -it /bin/sh) throws fata[0000] error response daemon: cannot start container a7bb092…: operation not supported

how can fix this?

well, turns out if machine had kernel update didn't restart yet docker freaks out. restarting machine fixed that. oops.
