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

Do I need to run a different command? or is not possible to install mariadb on oracle linux 7.

Thanks in advance

Answer 1

My installation of Oracle Linux 7.3 (group "Infrastructure Server") shipped with some mysql packages which may prevent the installation of mariadb packages. You need to remove them in order to install mariadb packages:

$ sudo yum remove mysql-community-libs mysql-community-common

I was then able to install the mariadb packages. Hope that helps!

Answer 2

The Oracle Linux 7 Anaconda installer enables the MySQL 5.5 repository by default during install, and thus installs the MySQL packages instead of the MariaDB packages.

To disable this during install, unselect the "Server-Mysql" repository in the Installation Source page on the Installation Summary screen. If you disable the repo, Anaconda will use only the packages in the base installer repository, which are the MariaDB packages.
