Description of problem: I am working on Openshift and trying to upgrade etcd to etcd3. When I try to just install etcd3 I get following error. I should be able to install etcd3 when v2 is installed. root@ip-172-31-26-90: ~ # yum install etcd3 [660/1048] Loaded plugins: amazon-id, rhui-lb, search-disabled-repos Resolving Dependencies --> Running transaction check ---> Package etcd3.x86_64 0:3.0.3-1.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved =============================================================================================================================================================$ ===================================================== Package Arch Version Reposito$ y Size =============================================================================================================================================================$ ===================================================== Installing: etcd3 x86_64 3.0.3-1.el7 rhel-72-$ xtras 9.4 M Transaction Summary =============================================================================================================================================================$ ===================================================== Install 1 Package Total download size: 9.4 M Installed size: 45 M Is this ok [y/d/N]: y Downloading packages: etcd3-3.0.3-1.el7.x86_64.rpm | 9.4 MB 00:00:03 Running transaction check Running transaction test Transaction check error: file /usr/bin/etcd from install of etcd3-3.0.3-1.el7.x86_64 conflicts with file from package etcd-2.3.7-4.el7.x86_64 file /etc/etcd/etcd.conf from install of etcd3-3.0.3-1.el7.x86_64 conflicts with file from package etcd-2.3.7-4.el7.x86_64 file /usr/bin/etcdctl from install of etcd3-3.0.3-1.el7.x86_64 conflicts with file from package etcd-2.3.7-4.el7.x86_64 Error Summary ------------- Version-Release number of selected component (if applicable): Red Hat Enterprise Linux Server release 7.2 (Maipo) How reproducible: Always Steps to Reproduce: 1. Make sure etcd-2.3.7-4.el7.x86_64 is installed 2. yum list shows etcd3 is available 3. yum install etcd3 and see error Actual results: Error can't install etcd3 Expected results: Should be able to install etcd3 Additional info:
Workaround: yum swap etcd etcd3
This is intended as the etcd3 must not remove etcd. Etcd contains user data which would be removed otherwise.
I think there needs to be an Obsoletes for installation of etcd3. Etcd3 will provide a clean upgrade for 2.3.7, but it should be an explicit user upgrade .
I would rather turn this into documentation/release notes.
Jan, What would be expected behavior after the fix?
conflicts would be the right thing? not obsoletes? no?
https://fedoraproject.org/wiki/Packaging:Conflicts "Keep in mind that implicit conflicts are NEVER acceptable. If your package conflicts with another package, then you must either resolve the conflict, or mark it with Conflicts:."
This it not going to be fixed in 7.3.1. The next target candidate is 7.3.2.
In 7.3.2 we should update etcd to be version 3. The etcd3 rpm (and container) will be deprecated.

This can be closed as the etcd3 component is officially obsoleted by etcd.
