I do not get any errors running this. What is your docker version, docker -D info and uname -a?

@elderone Please update to 1.1.2, I'm pretty sure this is fixed.

[Artimi]

I have this problem too.

When I try to build image based on this Dockerfile:

FROM ubuntu:12.04

RUN apt-get update
# for install add-apt-repository command
RUN apt-get -y install python-software-properties
RUN add-apt-repository -y ppa:biometrics/bob
RUN apt-get update
RUN apt-get -y install bob

In last step I get this:

groupadd: failure while writing changes to /etc/group
addgroup: `/usr/sbin/groupadd -g 102 utempter' returned error code 10. Exiting.
dpkg: error processing libutempter0 (--configure):

@cpuguy83 any thoughts on why it would be still broken on Docker 1.2.0? Perhaps an issue with devicemapper?

[joseblas]

@cpuguy83
I have the same problem from 1.14.

groupadd: failure while writing changes to /etc/group
addgroup: `/usr/sbin/groupadd -g 102 ssh' returned error code 10. Exiting.
dpkg: error processing openssh-client (--configure):
subprocess installed post-installation script returned error exit status 1

FYI, It's broken with a Ubuntu 12.04 image, but not with an Ubuntu 14.04 image. Running the FC20 shipped docker-io-1.2.0-2.fc20.x86_64 here.

[e0d]

The root cause seems to be an inability to write to /etc/passwd or /etc/group on 12.04

This minimal Docker file fail when run from FC20

FROM ubuntu:12.04.5
MAINTAINER e0d
RUN groupadd foo
EXPOSE 22 3000
ENTRYPOINT ["/bin/bash"]

[e0d]

The issue on FC20 is SELinux related, the ham-fisted work around is:

sudo setenforce 0

I'll work out exactly what's going on when I have a free moment.

[yosifkit]

I am unable to reproduce this and it seems to be related to SELinux. Closing for now.
