Installing Oracle18c in a Redhat8 vm running in OVM on Ubuntu 16.0.4. The curl command works wih no errors and downloads the preinstall rpm package, then the yum install fails with:
# yum -y install oracle-database-preinstall-18c-1.0-1.e17.x86_64.rpm

Yes I am using root. No there is not an oracle user created yet. I have verified the file exists and tried various permission combinations, even the dreaded 666.
