Bug ID: 1101123 Summary: docker package binary conflicts with docker-io Product: Fedora Version: 20 Component: docker-io Severity: medium Assignee: lsm5@redhat.com Reporter: dmcf@dcorking.com QA Contact: extras-qa@fedoraproject.org CC: admiller@redhat.com, golang@lists.fedoraproject.org, lsm5@redhat.com, mattdm@redhat.com, mgoldman@redhat.com, s@shk.io, vbatts@redhat.com

Description of problem: There is a file name conflict for /usr/bin/docker between 2 Fedora 20 packages.

Version-Release number of selected component (if applicable):

docker-1.5-10.fc20.x86_64 (f20 updates, a dockapp that provides a system tray for WindowMaker, XFCE etc.) docker-io-0.11.1-1.fc20.x86_64.rpm (f20 updates, a new Linux containerization app that has proven very popular)

How reproducible: Consistent.

Steps to Reproduce:

1. sudo yum install docker 2. sudo yum install docker-io

Actual results:

Transaction check error: file /usr/bin/docker from install of docker-io-0.11.1-1.fc20.x86_64 conflicts with file from package docker-1.5-10.fc20.x86_64

Expected results:

All packages in F20 should be able to co-exist unless a conflict is documented in the RPM file.

Since the conflict is only file naming, one of these packages could be patched to allow it to co-exist with the other.

Additional info:

Possible workaround that keeps docker working for me follows. (It allows docker-io to install, but I am not sure if docker-io is fully functioning.)

#!/bin/bash sudo mv /usr/bin/docker /usr/bin/wmdocker # user must change dock icons that link to docker to point to wmdocker sudo yum install docker-io --downloadonly cd /var/cache/yum/x86_64/20/updates/packages/ sudo rpm -Uvf --force docker-io-0.11.1-1.fc20.x86_64.rpm

The conflict probably also exists in rawhide. (unverified)

The upstream binary in both packages is 'docker'. Debian/Ubuntu rename their binary to 'docker-io' to deal with the conflict.

There is a plan to replace the 'docker' package with a renamed 'wmdocker' package in F21. (Bug # 1043676). However, that will take until F23 release to complete the Obsoletes/Expires process. In the meantime, any user with docker from F20 or rawhide will be unable to install docker-io, unless they use the workaround.
