hi @hafizhasssan I was able to install everything correctly using commands provided by you. I assume that the main issue you are also install MarriaDB packages(I see it in yum output) and yes there might be a conflict. So if you have installed MariaDB on your system it would be better to remove it firstly(surely prepare backup for database) and then install Percona-XtraDB-Cluster. ---

@hafizhasssan I still can’t reproduce this issue. Maybe you have enable mariadb’s repo and you are trying to install something else together with percona-xtradb-cluster? So what I suggest doing. 1 check if the files are still on the system ```auto ls -la /etc/my.cnf ``` if file exists - `rpm -qf /etc/my.cnf` ```auto ls -la /usr/lib64/mysql/plugin/dialog.so ``` if file exists - rpm-qf `/usr/lib64/mysql/plugin/dialog.so` Please provide me with the results. The next step I would suggest disabling MariaDB’s repo and trying to install percona-xtradb-cluster ---

@hafizhasssan there are a few ways how to do this First of all you need to get it’s name yum repolist should help you I assume you will get the following ```auto mariadb-main MariaDB Server mariadb-maxscale MariaDB MaxScale mariadb-tools MariaDB Tools ``` To disable you can do the following modify `/etc/yum.repos.d/mariadb.repo` and `set enabled = 0` `sudo sed -i 's:enabled = 1:enabled = 1:g' /etc/yum.repos.d/mariadb.repo` or ```auto yum-config-manager --disable mariadb-main yum-config-manager --disable mariadb-maxscale yum-config-manager --disable mariadb-tools ``` or `sudo yum install --disablerepo=mariadb-main percona-xtradb-cluster` Additionally I would suggest running yum clean all before running yum install ---
