I have installed MariaDB 5.3.3 on a Centos 6 server. In order to do that, I had to issue this command before installing the MariaDB-server rpm:

rpm -e --nodeps mysql-libs

And now mariadb and all the other software in the server is working fine.

Today I tried to upgrade the packages in my server the packages were successfully upgraded with the only exception of postfix which I can't install because of this error:

Running rpm_check_debug
ERROR with rpm_check_debug vs depsolve:
mysql-libs is needed by postfix-2:2.6.6-2.2.el6_1.x86_64
** Found 1 pre-existing rpmdb problem(s), 'yum check' output follows:
2:postfix-2.6.6-2.1.el6_0.x86_64 has missing requires of mysql-libs
Your transaction was saved, rerun it with: yum load-transaction /tmp/yum_save_tx-2012-02-13-09-487yg1lQ.yumtx
.. install failed!

Could anyone help me overcome this problem? I am pretty sure that the software in the mysql-libs package is already installed by mariadb packages but this information ins not in the rpm system.

It's not so much that the package is conflicting, it's more that you uninstalled a postfix dependency (postfix mysql integration) in getting MariaDB-server to install.

If you reverse your steps and reinstall mysql-libs again, you'll solve this problem (but probably lose MariaDB). You might just get lucky by installing the compat-libs however.

(Given the lack of answers, it might be worth it. I'll give it a shot when I get a spare moment on a Cent 6 VM)

Add the remi repository to your rpm repo by doing the following;

rpm -Uvh
rpm -Uvh

Then try to install the mysql-compat rpm...

rpm -Uvh

And if that works, see if you can update
