yum install openssl openssl-devel openssl096 fails with
IOError - # 2 - No such file or directory
stracing shows that it's looking for the openssl i686.hdr file which it has not
bothered to download even though it's present in header.info and the existing
openssl package is the i686 version.

needinfo - yum -d 5 install 
see what that tells you.

Works for me.

* If openssl is not installed at all, running yum gives a traceback, because
openssl is a requirement of python:

ImportError: libssl.so.2: cannot open shared object file: No such file or directory

* If openssl is installed and yum works, I can install i686 packages fine, e.g.
"yum -y install kernel-bigmem" installs kernel-bigmem-2.4.18-3.i686.rpm 

* If I rm -rf /var/cache/yum and run yum, it downloads all headers of packages
not installed already.

My mistake.  Somehow I managed to install the i386 openssl package on this
machine even though it's an Athlon and runs i686 fine.	I've been installing
updates by going to redhat's web site and downloading them from the advisory
page.  I must have clicked on the wrong link.  

It appears the bug is actually that yum doesn't try to upgrade the architecture
when it's downloading packages, but it does try to upgrade the architecture
when it's resolving dependencies.  It should be consistent.

This is in the man page. set exactarch=0 if you'd like yum to change arch on a
package updates.

Keep in mind changing arch on an update CAN be very very dangerous.

OK, but it looks like yum is not handling exactarch=1 correctly as it still
tries to resolve dependencies against the upgraded arch.

BTW "yum update openssl" doesn't display this behavior.
Only "yum install openssl" does.
It looks like pkgaction.installpkgs doesn't realize that a package is already
installed unless it was installed with the bestarch.  If it doesn't find (name,
bestarch) then it should just look up the name (or maybe (name, arch)?) to see
if another arch of the package is installed.  If exactarch is set, it should
determine the installed arch* and update to that.  If exactarch is not set, it
should update to the bestarch.
*nevral.py doesn't seem to allow this?  Is the arch in nulist always the
installed arch when exactarch=1?

Seth, can you comment here?  Is this really a bug?  Does this belong in Yum's
bugzilla rather than a Legacy issue?

I'm not even sure this is a bug - but it's definitely not fedora legacy's problem.

close this - and if it can be replicated refile in yum bugzilla.
