error upgrading from 10.1 to 10.2

hello -

i have attempted to upgrade to 10.2 on my centos-7 by following these steps:

1) sudo yum -y remove MariaDB-server MariaDB-client ;

2) mv MariaDB.repo MariaDB.repo-OLD; and created new MariaDB.repo as outlined here

3) sudo yum -y install MariaDB-server MariaDB-client ;

however, i get the following error:

Downloading packages:

MariaDB-10.1.30-centos7-x86_64 FAILED

http://yum.mariadb.org/10.2/centos7-amd64/rpms/MariaDB-10.1.30-centos7-x86_64-server.rpm: [Errno 14]

HTTP Error 404 - Not Found ] 0.0 B/s | 0 B --:--:-- ETA

Trying other mirror.

some Stack-Overflow suggestions are to include the following commands between step two and three:

rm -rf /var/lib/mysql; rm /etc/my.cnf ;

however, i would think that yum/rpm would take care of this for me.

for fun, i created a completely fresh new centos-7 (no former installs, of course) and the installation worked fine.

suggestions? dare i delete /var/lib/mysql ? or should i just attempt something more innocent like

mv /var/lib/mysql /var/lib/mysql-RENAMED; mv /etc/my.cnf /etc/my.cnf-RENAMED;

thank you very much.

EDIT: my silly mv /var/lib/mysql /var/lib/mysql-RENAMED; idea did not work. its as if yum is remembering 10.1.30 and will not upgrade for some reason.

yum clean all;

this is from trevor, the moderator at the centos-7 forum.
