What does it say? Is it failing on a dependency problem? It is known that "downgrade" doesn't resolve deps. as well as upgrade. You might want to try "yum history undo" if you are trying to do a downgrade to reverse some problem (although at this point in F-12 it might be to a version of gnome-panel that no longer exists).

Comment 2 Jasper O'neal Hartline 2010-05-06 22:56:49 UTC
I will attach the output, I attached it last time it doesn't seem to have attached it properly.

Yum output

Yum output for not being able to downgrade to a version of gnome-panel that does exist, but yum downgrade gnome-panel-libs does actually work. Should work for both I would assume.

Comment 4 James Antill 2010-05-07 04:05:29 UTC
 Yeh, as I said, it's the fact the depsolver doesn't understand what is happening well enough. However I thought it'd fail, not do this:

--> Running transaction check
---> Package gnome-panel-libs.i686 0:2.28.0-13.fc12 set to be updated
---> Package gnome-panel-libs.i686 0:2.28.0-16.fc12 set to be erased
--> Processing Dependency: gnome-panel-libs = 2.28.0-16.fc12 for package: gnome-panel-2.28.0-16.fc12.i686
--> Running transaction check
---> Package gnome-panel.i686 0:2.28.0-16.fc12 set to be erased

...which we should fix.

bug 549404 says:
> it would be nice if yum tried harder to do a consistent downgrade

> things, which can cascade into removing most of one's system.


Comment 6 James Antill 2010-09-14 16:46:55 UTC
Not really a dup as this one is fixed ... we won't do cascade removals now, but we can still install other arch packages.
