Description Stijn Hoop 2008-04-08 07:36:20 EDT
Description of problem:

I could not install perl-Test-Simple-0.62-38.fc8.x86_64 on my x86_64 box by usin
g 'yum install perl-Test-Simple.x86_64' because yum added a dependency on
perl.i386, which conflicted with the already installed perl.x86_64.

However manually downloading the RPM and entering 'yum localinstall
perl-Test-Simple-0.62-38.fc8.x86_64.rpm' did work.

Version-Release number of selected component (if applicable):

yum-3.2.8-2.fc8.noarch

How reproducible:

On my system, everytime.

Steps to Reproduce/Actual results (copy and paste of session):

output of yum -d9 install perl-Test-Simple.x86_64

As requested by f13 on IRC, here's a complete yum -d9 log of the 'yum install
perl-Test-Simple.x86_64' command. In particular yum seems to think that it
needs to add both perl.x86_64 and perl.i386.
Comment 2 Seth Vidal 2008-04-10 15:05:47 EDT
Did you notice that the perl-Test-Simple version from your two tests are different?

Is it possible the dep-set changed in -38 from -36?
Comment 3 Stijn Hoop 2008-04-11 02:30:00 EDT
Err, no I did not see that, good catch.

So for the perl-Test-Simple -36 package, yum really wants to find the exact
corresponding perl version (4:5.8.8-36.fc8). This means that the currently
installed perl version does not suffice (4:5.8.8-38.fc8), and in turn yum goes
off  to find another match -- which it finds in the i386 version, therefore it
wants to install that one.

2 questions left for me:

- why does yumdownloader find a newer version than yum ?
- is it desired behaviour to install an i386 dependency for an x86_64 package ?
Comment 4 Seth Vidal 2008-04-11 09:43:35 EDT
yumdownloader, if run as a user, grabs a new version of the metadata which often
means a different mirror - sometimes one that is more current

and it's not thast installing an i386 is 'desired' necessarily but it is
sufficient and when it has no other choice that's what yum goes with.
