docker dependency version check fails

[mit2nil]

1. Trying to install nvidia-docker 2.0 on Ubuntu 16.04 machine and getting failure due to mismatched docker-engine package version.

As per https://github.com/NVIDIA/nvidia-docker/wiki/Frequently-Asked-Questions#platform-support, legacy official package docker-engine is supported but there are no details on version. I am getting failure for 17.03.0~ce-0~ubuntu-xenial which is not that old (https://www.ubuntuupdates.org/package/docker_new/ubuntu-xenial/main/base/docker-engine)

2. Commands used

docker-engine 17.03.0 is not supported. The official stable release for the 17.03.x series is docker-ce 17.03.2

Hi,

how do I re-open the issue? I think this issue is still relevant.

I removed docker-engine and moved to docker.io from canonical and installed latest version 1.13.1 for Ubuntu 16.04 (https://packages.ubuntu.com/xenial-updates/docker.io) But nvidia-docker 2.0 installation is still failing.

nilay@localhost:~$ dpkg -l | grep docker
ii  docker.io                                  1.13.1-0ubuntu1~16.04.2                       amd64        Linux container runtime

Do we really need to get exactly 1.12.6 nothing above that is supported? As an experiment, I also installed 1.12.6 from zesty on Ubuntu 16.04 (xenial) (https://packages.ubuntu.com/zesty/docker.io) which went fine but there was a slight difference in name and and that was not acceptable to nvidia-docker 2.0

nilay@localhost:~$ dpkg -l | grep docker

I also tried various stable releases of docker-ce for ubuntu 16.04 from https://download.docker.com/linux/ubuntu/dists/xenial/pool/stable/amd64/ before this and none of them were supported. This is also evident from the error message in above code snippet. In which case, https://github.com/NVIDIA/nvidia-docker/wiki/Frequently-Asked-Questions should not say that stable releases of docker-ce are supported.

Thanks, Nilay

Can you post the error messages with stable versions of docker-ce?

[mit2nil]

It just complains that it dependencies are not met without commenting on docker-ce version.

nilay@localhost:~$ dpkg -l | grep docker

Yes, because you asked to install version 1.12.6, and docker-ce didn't exist at this time.

[mit2nil]

Aha my bad. ok it is working with docker-ce.
