[root at virtfed ~]# rpm -q anaconda
package anaconda is not installed
[root at virtfed ~]# rpm -qa|grep anaconda
anaconda-yum-plugins-1.0-5.fc12.noarch

I think I have something yet to fix..... ;-(
I fact, due to the strange fc11 in the yum info result... now I
checked and I have this on my system:
[root@ ~]# rpm -qa|grep fedora-release
fedora-release-notes-12.0.2-1.fc12.noarch
fedora-release-12-2.noarch
fedora-release-11-1.noarch

[root@ ~]# rpm -qf /etc/fedora-release
fedora-release-11-1.noarch
fedora-release-12-2.noarch

and while going to complete upgrade with package-cleanup --orphans
info, it gives as output almost all the fc12 packages installed.....
(1255 of 1316 of output)

so it seems it actually thinks to be in f11 yet (from a yum point of view...)?

probably something to fix due to the manual steps....
What should I do? remove the fedora-release-11-1.noarch rpm?

Thanks in advance,
