output of 'yum install python-twyt'

Description of problem:

rawhide-ish machine.  Run 'yum install python-twyt' from the command line, get whined about font packages conflicting.

Filing this as a yum bug on due to the following irc exchange:

< nim-nim> ajax: skvidal asked me to add the explicit conflict to help 
           yum detect bad upgrades
< ajax> the "bad" upgrade here being me trying to install some python 
< nim-nim> ajax: yum is supposed to detect all this and upgrade 
< nim-nim> ajax: if you've find a case where yum is confused, open a yum

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

So the basic update path just works, and something else must be confusing yum or pinning the old conflicting packages on ajax' system
Comment 2 Adam Jackson 2009-01-04 11:07:01 EST
Hilariously, I can't upgrade yum (at least not with the rawhide repos enabled) to see if this is fixed already, for much the same reason: python abi change -> inkscape -> poppler -> openoffice -> fonts -> doom.

I installed yum-3.2.20-5.fc10 from koji by hand, but it produces the same failure when trying to install rawhide python packages.
Comment 3 Nicolas Mailhot 2009-01-04 11:09:54 EST
dejavu-fonts-compat.noarch should have cleaned up the old dejavu-fonts package and is in the transaction set, so yum is doing something strange
Comment 4 seth vidal 2009-01-04 11:19:59 EST
If a pkg contains files which conflict with another pkg then you have to have a Conflicts: line in the spec file - this is listed in Fedora's Packaging Guidelines. It is nicer b/c it means yum can tell if there is a conflict without having ALL of the file metadata (including checksums).

There appears to be a conflict that we cannot upgrade out of.

Ajax: have you made any changes to your yum.conf?

Not that I'm aware of.  yum.conf from the affected machine is attached.
Comment 6 Adam Jackson 2009-01-04 11:28:26 EST
Well, okay, not in a way that should affect this.  installonly_limit is clearly my own doing.
Comment 7 James Antill 2009-01-04 14:08:15 EST
 I'm pretty sure this is obsoletes related, not conflict. From a list obsoletes I see:

dejavu-fonts-compat.noarch            2.28-1.fc11                      rawhide  
    dejavu-fonts-experimental.noarch  2.24-3.fc9                       installed
dejavu-fonts-compat.noarch            2.28-1.fc11                      rawhide  
    dejavu-fonts.noarch               2.24-3.fc9                       installed

...my guess is that the 'yum install python-twyt' path is only processing one (or maybe zero) of the above obsoletes. We might have fixed this already in 3.2.20-8 ... but can you run the above install command with "-d 9", as that'll hopefully tell us what obsoletes that single update line is doing.

Comment 9 James Antill 2009-01-04 19:04:14 EST
 This should now be fixed in upstream commit: f203d754c952c4f117ed8ddbb09dda9ba237dacd

 This'll be in 3.2.21 which should be released "soon". Or you can just "yum update deja\*" for the time being. Or you can try "Running an upstream yum-3.2.* locally" instructions from:


...to get around it.
Comment 10 James Antill 2009-01-04 19:05:42 EST
 Or apply the fix by hand, if you're really feeling lucky:)

Comment 11 Adam Jackson 2009-01-04 20:59:56 EST
I'm a lucky kind of guy.  That fixes it, thanks!
