yum can be configured to try to resolve such errors by temporarily enabling  
disabled repos and searching for missing dependencies.  
To enable this functionality please set ‘notify\_only=0’ in /etc/yum/pluginconf.d/search-disabled-repos.conf

Error: Package: percona-xtrabackup-24-2.4.12-1.el7.x86\_64 (percona-release-x86\_64)

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

Hello [vu3mmg](https://www.percona.com/forums/member/42497-vu3mmg) thanks for asking

First of all you have to do

```auto
yum install epel-release

```

and then after that

```auto
yum install Percona-XtraDB-Cluster-server-57

```

See how you get on?
