Good news!
Based on your tips, I ran the following command excluding the packages in conflict.

yum --exclude samba*,libldb*,libsmbclient,libwbclient,pyldb* update

So, I updated everything except the excluded packages.

Thank you all for your support, Nick and Tony. I really appreciated that.

Now I will wait for samba package release for the next updates.

Thank you, Tony!
I'll try to update using your yum command with that exclude packages.
Our CleaOs installation isn't in production yet, it's so closed, so I'll rest during the weekend and I'll resume at the next monday.

Best weekend to all of you and thank you all for your support!

Nick, granted. The OP is free to limit which repositories he wishes to access, and would expect him to do so. My example gives an indication of what is required to ignore the samba upgrade on my system.

In fact when I run the example for my system I get no "No packages marked for update". Remove the excludes and get a slew of samba packages and "Protected multilib versions: libldb-1.1.20-1.el7_2.2.i686 != libldb-1.1.25-1.el7_2.x86_64" as a final line.

That will also open you up to the centos* unverified, and the testing repos. I'm not convinced that is a good idea unless you are prepared for the fallout.

Dany - I was up-to-date just before the flawed samba packages were released to no real problem for me to pause my updates. I also have quite a number of i686 packages installed to support a 32-bit application so I get the multilib problem at times when the i686 and x86_64 updates are not released simultaneously.

In my case to exclude samba I would require (that is one long line, and watch for split words. In my case the forum software has split "libsmbclient" between two lines)

yum --enablerepo=* update -x samba* -x libwbclient -x libreplace-samba4.so -x libldb* -x libsmbclient -x pytalloc -x pyldb -x libtalloc

Nick, I will go crazy,

yum update --exclude=*.i686,libldb

Results in:

I think the samba-libs package is OK because it seems to require only the older libldb. I suspect it is the libldb itself so try:

yum update --exclude=*.i686,libldb

What I find odd is that I don't see libldb 1.1.25 in clearos-centos-updates.

Nick, unfortunately your updated command

yum update --exclude=*.i686

result in:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Maybe it's because it's the Samba package that is creating the conflict. Do not you think?
How do I exclude all Samba from the update?

Try my updated command.

Tony, thank you for your reply.
You are right, it's Samba!

[root@0dc00215 ~]# rpm -q --whatrequires libldb
samba-libs-4.2.3-12.v7.x86_64

So, are you advising to not upgrading anything until the present hold on the Samba upgrade is finalized and tested?

But I do not understand as I'm not doing a upgrade, I would like to just *update* my current 7.1 installation. I have a couple of hundred packages to upgrade. When I tried to do the update, my bad luck, I did it just during the DNS problem and I got all those 404 errors. Apparently I had repositories pointing to those testing repo due the failure.

Oh, gosh! All I wanted was to run yum clean all / yum update and maintain the system up-to-date and clean.

Is there any way to update everything else except the Samba package?

Tony, thank you again for your time. I really appreciated that.

That was a typo. It should have been:

yum update --exclude=*.i686

Do you have any i686 rpms installed? "rpm -qa | grep i686"

I can reproduce this multilib error, but when I look at :-

[root@sandra ~]# rpm -q --whatrequires libldb

samba-libs-4.2.3-12.v7.x86_64

[root@sandra ~]# 

I am not upgrading anything until the present hold on the samba upgrade is finalized and tested....

I would to like to post some more information.
The package that is in conflict is libldb.

yum list all libldb

Installed Packages
libldb.x86_64 1.1.20-1.el7_2.2 @clearos

Available Packages
libldb.i686 1.1.25-1.el7_2 clearos-centos-updates
libldb.x86_64 1.1.25-1.el7_2 clearos-centos-updates

So I tried to install both packages (i686 and x86_64) to synchronize the versions.

yum install libldb.x86_64 libldb.i686

At the end, I got "Multilib version problems" error for the following packages:

Protected multilib versions: libldb-1.1.20-1.el7_2.2.i686 != libldb-1.1.25-1.el7_2.x86_64

He looks like it needs the version 1.1.20..i686, but this package does not exist in the repo.

If I try to upgrade instead update, I got the same.

Should not this package version is stored in the repo?

I'm not sure how to get rid of this one. Anyone?

You can try updating the other packages one by one, but it won't resolve the dependency error.

FYI,
libldb-1.1.20-1.el7_2.2.i686 is available, but not installed.

If I try to update libldb-1.1.17-2.el7.x86_64, so I go the Protected multilib versions error.

I can't figure out what I would to do to fix it!

Nick, thank you again for your support!

Unfortunately,

 yum update --exclude=i686

doen't work, the error still ocurrs:

Error:  Multilib version problems found. This often means that the root

       cause is something else and multilib version checking is just

       pointing out that there is a problem. 

[...]



Protected multilib versions: libldb-1.1.20-1.el7_2.2.i686 != libldb-1.1.25-1.el7_2.x86_64

Have you another clue?

That happened for a while in the past in 6.x. Try:

yum update --exclude=i686

I enabled clearos-centos repo too.
It seems that the dependencies were corrected at least so far.

The error now is so weird:

Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

1. You have an upgrade for libldb which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libldb of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libldb.otherarch ... this should give you an error
message showing the root cause of the problem.

2. You have multiple architectures of libldb installed, but
yum can only see an upgrade for one of those architectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.

3. You have duplicate versions of libldb installed already.
You can use "yum check" to get yum show these errors.

...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).

Protected multilib versions: libldb-1.1.20-1.el7_2.2.i686 != libldb-1.1.25-1.el7_2.x86_6

Any clue?

clearos-centos is also disabled. If you need one you should enable both.

Bingo! I enabled

clearos-centos-updates

repo, it was disabled. I got some package dependencies yet, but less than last

yum update

. Any clue?

Last, but not least, could I apply

Nick, thank you very much for your support!

Can you check your repos:

yum repolist

If clearos-centos and clearos-centos-updates are disabled you may need to enable them again if you already have packages installed from them.

As I said in previous post I'm in trouble with package dependencies now after I applied some fix to the repo list.

Any help will be welcome!

I saw the notes about a certain DNS failure in last April. Some week ago I tried to update my server and the update was broked with 404 error. I think that was during that failure.
Checking the /etc/yum.repos.d/ directory there was a clearos.repo.rpmnew file there. So I backed up the original clearos.repo file and I copied the *.rpmnew as clearos.repo.
Voilá, the repositories are back. But I don't know if they are the correct ones. But all seems to be Ok now, though I have some broken dependencies!

Here my new clearos.repo as following:
