CentOS repository contains ruby conflicts - unable to run yum update plainly

this is expected behaviour. if you want to do update, just exclude ruby from the update command

yum update --exclude=ruby*

please use yum update --exclude=ruby*

Let's just ship yum config for forcing ruby to 1.8.7. I'll take this bug and make it so you can yum update without ruby conflicts.

Review: https://review.openstack.org/161323

I believe this is now Critical due to its impact on patching OpenStack.

I disagree with the RCA on this bug: the problem isn't with yum configuration, it's with the way we've packaged ruby-2.1. We should have called this package ruby21 (so that it's not an upgrade from ruby-1.8.x) and made it install ruby binary at /usr/bin/ruby21 (so that it doesn't conflict with ruby-1.8.x).

Either that, or give up on Ruby 1.8 backwards compatibility on target nodes as we already have on Fuel master.

P.S. Second part of the ruby21 requirement (/usr/bin/ruby21) is optional, instead we can declare that ruby21 conflicts with ruby and not allow to install both versions on the same system, which is closer to the current situation, but still resolves the updates problem.

I've renamed this one. Package is placed under centos-fuel-6.1-stable repo.
As follows:
---
Provides: ruby(abi) = 2.1
Provides: ruby-irb
Provides: ruby-rdoc
Provides: ruby-libs
Provides: ruby-devel
Provides: rubygems
Conflicts: ruby < 2.1
---
Well, speaking frankly, I feel this hack is not quite correct. But fastest indeed.
We should make "Provides: ruby21" and recompile all related stuff according to this. It could help to avoid possible problems when upgrading.

UPD: mispasted.
+Name: ruby21

We are trying to install all ruby versions onto one system at one time. This way iso-make-system works now.

1. We have to fix astute.spec to "Depends: ruby21" instead of "Depends: ruby = 2.1.1"
2. Astute tries to install new ruby21 over existing installed ruby-1.8.7.

Patches to make system in order to prevent this to happen are in testing stage.

    Related-Bug: #1403088

    Change-Id: Ie79b5c9cd953b7ab520aeba532bbf9091971240d

Let me explain details
1. Ruby-1.8 and ruby-2.1 are totally incompatible with each other. Moreover, packages which are provided by every ruby are incompatible too. There is no way to cleanly install ruby-1.8 and ruby-2.1 together.
2. We have a bunch of gems total number 131 which have to be recompiled when ruby changes
3. ISO make build system is not aware of ruby problem and tries to install ruby-1.8 and ruby-2.1 together.
4. There is no convenient way to modify ruby package without touching the code.
5. There are a list of external products which are using different ruby versions. Astute=2.1, Nailgun=1.8 Eg.
6. In order to test overall picture one must built ISO and wait until all tests are passed. It's quite a long run.

We renamed ruby-2.1 to ruby21, repackaged all the dependencies stuff, fixed external products' specs. It builds locally but have some problems in mirrors we are fixing right now.

1. We need to #FIXME there after cleaning up our mirrors.
2. Also we have to remove ruby-2.1.1 from all our mirrors. This will make all related jobs green again

build_staging_mirror completed
iso with final fixes is on the way

I need some light on versions to choose for 6.1

1.
- rubygem-net-ssh-2.2.2 requires rubygems >= 1.3.7 - broken but on ISO
- rubygem-net-ssh-2.8.0 - ok but not in ISO

2.
- rubygem-net-ssh-gateway-1.1.0 requires rubygems >= 1.3.7 - broken but on ISO
- net-ssh-gateway-1.2.0 - ok but not on ISO.

All other parts are fixed.

5.1.2 builds are green, but several 6.1 staging iso builds later the iso build is still failing during ruby package dependency resolution.
