Description Jason Joyce 2018-06-22 20:59:41 UTC 
Description of problem:
When upgrading from an openvswitch version prior to 2.7.3-2 any optional packages (ovn-docker, etc.) in the new version are still installed.

Version-Release number of selected component (if applicable):
openvswitch-2.6.1-15.git20161206.el7ost
openvswitch-2.9.0-19.el7fdp.1

How reproducible:
Always
 then upgrade to openvswitch-2.9.0-19.el7fdp.1 via yum


Steps to Reproduce:
1. Install openvswitch-2.6.1-15.git20161206.el7ost
2. yum upgrade openvswitch 

Actual results:
openvswitch-ovn-docker-2.6.1-16.git20161206.el7ost is still installed


Expected results:
Only openvswitch-2.9.0 packages are left on the system

Additional info:
Obsoletes need to be added for all optional sub-packages
Comment 2 Timothy Redaelli 2018-06-24 11:28:32 UTC 
Probably it's better to put some:

Requires: openvswitch-subpackage = %{version}-%{release}

for example python-openvswitch and openvswitch-ovn-common may have:
Requires: openvswitch = %{version}-%{release}

and the other ovn packages may have:
Requires: openvswitch-ovn-common = %{version}-%{release}

I agree we should have these interdependencies.  The issue may not be completely clear, though.  

The issue here is that those optional sub-packages are actually not part of builds anymore, so not available.  If the change was made to add the Requires as specified, yum would actually fail because the optional sub-package doesn't exist for the newer openvswitch package.  

To solve this, in addition to the Requires, the base openvswitch package should also have:

Obsoletes:  <subpackage> < %{version}-%{release}

for each of the optional subpackages.
Comment 4 Flavio Leitner 2018-06-28 12:56:50 UTC 
If we don't want that package to remain installed and it doesn't exist anymore, then our only option is to obsolete it in the main package. Just be careful to limit the version to allow us to bring it back in the future if needed.

Other restrictions might be too heavy, because we ship all packages at the same time, so yum should update all installed rpms in a smooth way and if we need to replace any rpm with a debug enabled one, we don't need to upgrade all others.

Comment 6 Rick Alongi 2018-07-19 19:31:07 UTC 
I installed all of the 2.6.1.15 packages:

[root@netqe20 ~]# yum list installed | grep openvswitch
kernel-kernel-networking-openvswitch-vm100.noarch
openvswitch.x86_64                    2.6.1-15.git20161206.el7ost

openvswitch-ovn-vtep.x86_64           2.6.1-15.git20161206.el7ost

I then pointed to an RHOSP repo (RHOSP 13).  When I do a yum provides openvswitch, I see:

I do a yum update openvswitch and then a yum update openvswitch-ovn*.  After this, I checked for what was now installed and see that the obsoleted openvswitch-ovn-docker.x86_64 2.6.1.15 package remains.

[root@netqe20 home]# yum list installed | grep openvswitch

I removed all packages referenced and re-installed them at 2.6.1.15:
