Description dipu 2013-11-05 09:48:17 UTC

Description of problem:
yum update trying to install 32 bit package of suitesparse as an update for suitesparse 64 bit package. If you try yum install suitesparse it behaves differently.

Version-Release number of selected component (if applicable):
yum-3.2.29-40.el6.noarch
suitesparse-3.4.0-7.el6.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Kickstart a Red Hat Enterprise Linux Workstation release 6.4 machine(x86_64)
2. Install suitesparse package (suitesparse-3.4.0-7.el6.x86_64)
3. Subscribe rhel-x86_64-workstation-optional-fastrack-6 channel to the system
4. Try yum install suitesparse and yum update suitesparse in the machine and you will see different results

yum install package and yum update package should give same result

Additional info:
The channel rhel-x86_64-workstation-optional-fastrack-6 only have i686 arch of suitesparse-3.4.0-8.el6, but yum shouldn't try to install suitesparse.i686 0:3.4.0-8.el6 as an update of suitesparse-3.4.0-7.el6.x86_64

> yum update suitesparse shoudln't try to install suitesparse.i686 0:3.4.0-8.el6 
as an update of suitesparse-3.4.0-7.el6.x86_64

 It's a newer version, why wouldn't it be installed?

> yum install package and yum update package should give same result

 They should, but this is a weird corner case ... the recommended way to change arches is to use a versioned obsoletes. At which point yum install would do the same thing.
 In this case yum install is getting confused because of the arch difference and the fact that the latest version of the default arch is installed. While the commands do behave differently, and we try hard to make them behave the same way ... this is a very corner case and would be resolved by fixing the packaging.
