Bug 818208

It would seem that samba needs a dependency on libwbclient.

Can you tell what version of libwbclient package do you have ?

I didn't have _any_ version of libwbclient. That's the point -- the samba packages don't tell yum that libwbclient is needed.

Now that I've installed it manually, yum is happy to let me remove it without flagging it as a dependency issues and forcing samba packages to be removed as well:

jik2:~!999$ sudo yum remove libwbclient

Is this ok [y/N]:

What samba-1:3.6.5-85.fc17.1.x86_64 requires is libwbclient.so.0()(64bit). The latter is provided by libwbclient-1:3.6.5-85.fc17.1.x86_64 so yum should be able to solve the dependency easily.

You can check yourself:
samba -- http://koji.fedoraproject.org/koji/rpminfo?rpmID=3087763
libwbclient -- http://koji.fedoraproject.org/koji/rpminfo?rpmID=3087771

$ rpm -q --whatprovides 'libwbclient.so.0()(64bit)'
samba4-libs-4.0.0-43alpha18.fc17.x86_64
libwbclient-3.6.5-85.fc17.1.x86_64
$ rpm -ql samba4-libs | grep libwbclient
/usr/lib64/samba/libwbclient.so.0
/usr/lib64/samba/libwbclient.so.0.9
$ rpm -ql libwbclient | grep libwbclient
/usr/lib64/libwbclient.so.0
$ 

There is some confusion here.

ok we will investigate how to handle this, the issue is in the samba4 packages they should not provide 'libwbclient.so.0()(64bit)' as in the samb4 case libwbclient is a private library.

Hello.
I have the same problem, but on my F16, 32bit !
I am trying to do yum update, but it fails:

Any help to solve this ?
Thank you. :)
