Magic: convert CentOS 7 to Oracle Linux

I found this post https://www.digitalocean.com/community/questions/how-can-i-install-oracle-11g


curl -O https://linux.oracle.com/switch/centos2ol.sh
chmod 777 centos2ol.sh
sudo sh -c ./centos2ol.sh

sudo yum distro-sync

I get this:


Transaction check error:

sudo yum install oracle-rdbms-server-11gR2-preinstall

sudo reboot now

At this point, you can try to install Oracle DB http://www.oracle.com/technetwork/articles/servers-storage-admin/ginnydbinstallonlinux-488779.html
