Delta RPMs disabled ....

Hi,

today I have 5 updates in Yum Manager  and I ask to apply....

Package MariaDB-client.x86_64 0:10.1.26-1.el7.centos
Package MariaDB-common.x86_64 0:10.1.26-1.el7.centos
Package MariaDB-devel.x86_64 0:10.1.26-1.el7.centos
Package MariaDB-server.x86_64 0:10.1.26-1.el7.centos
Package MariaDB-shared.x86_64 0:10.1.27-1.el7.centos

but then again shows me that they are available in List of available packages for update ...

By reviewing the information after I apply, at the end I have the following message

Delta RPMs disabled because /usr/bin/applydeltarpm not installed.

It seems that you've minimal centos with some packages missing. To solve the issue install deltarpm.

yum install deltarpm
