MySQL/MariaDB upgrade error

I tried to upgrade MySQL 5.6 to MariaDB 10.3 last week within the cpanel upgrade tool withtout succes so I made it in terminal. MariaDB upgrade was succesful but now I stuck with broken dependencies (I guess) blocking other uprade. Cpanel seems to still see MySQL 5.6 as the default db server but can't find the package creating conflict with mariadb package: [2019-07-04 23:00:39 -0400] file /usr/share/mysql/norwegian/errmsg.sys from install of MySQL56-server-5.6.44-1.cp1178.x86_64 conflicts with file from package MariaDB-server-10.3.16-1.el7.centos.x86_64 How can I remove the Mysql56 packages ?
