A "me too" with more details:

I have upgraded from F12 to F14 via DVD ISO image (no preupgrade), and I had the same problem. The problem is that F12 apparently has newer version of vim, so it did not get upgraded to the F14 package, which has lower version:

Before:
$ rpm -qa|grep vim
vim-filesystem-7.3.029-1.fc12.x86_64
vim-minimal-7.3.029-1.fc12.x86_64
vim-enhanced-7.3.029-1.fc12.x86_64
vim-common-7.3.029-1.fc12.x86_64

I then did the following:
# rpm -e --nodeps vim-filesystem vim-minimal vim-enhanced vim-common
# yum -y install vim-enhanced vim-minimal

and the versions now are:
$ rpm -qa|grep vim
vim-enhanced-7.2.446-2.fc14.x86_64
vim-common-7.2.446-2.fc14.x86_64
vim-minimal-7.2.446-2.fc14.x86_64

So there are two problems:

1. F14 has older version of vim than F12 without increasing the package Epoch.
2. Anaconda should probably prefer packages for the "new distribution", even though existing ones have higher or the same version. This should definitely be the case when the existing package will end up with broken dependencies after the upgrade [meta: should I report it as a separate bug of anaconda?]

I have seen a similar problem with many other packages - after the upgrade, there remained many F12 packages with broken dependencies, instead of being upgraded to the F14 version.

Hoooooaaaaaaaaahhhhh !!!! That fixed things perfectly :-) !!!!


Jan: I am having a few other odd problems w/ NFS client & CIFS mounts, I wonder if they are the same symptom you diagnose in problem 2 above (I notice several dozen FC12 packages still installed) ? Anyway, well done, I am up & running w/ vi(m) :-) !!!!

I have reproduced the problem on a freshly installed F12 machine upgraded to F14,
and reported the results as a bug in anaconda. See bug #651419.

So the problem here is that upgrade path from F-12 -> F-13/14
is now completely broken:

[tasaka1@localhost ~]$ koji latest-pkg dist-f12-build vim
Build                                     Tag                   Built by
----------------------------------------  --------------------  ----------------
vim-7.3.029-1.fc12                        dist-f12-updates      karsten
[tasaka1@localhost ~]$ koji latest-pkg dist-f13-build vim
Build                                     Tag                   Built by
----------------------------------------  --------------------  ----------------
vim-7.2.411-1.fc13                        dist-f13              karsten
[tasaka1@localhost ~]$ koji latest-pkg dist-f14-build vim
Build                                     Tag                   Built by
----------------------------------------  --------------------  ----------------
vim-7.2.446-2.fc14                        dist-f14              mtasaka

And the location of libperl.so is moved from
perl-libs-4:5.10.0-96.fc12.x86_64
/usr/lib64/perl5/5.10.0/x86_64-linux-thread-multi/CORE/libperl.so

to:
perl-libs-4:5.12.2-136.fc14.x86_64
/usr/lib64/perl5/CORE/libperl.so

Now vim-7.3.055-1.fc13 is in testing. Karsten, would you also upgrade
F-14 vim?
