Dnf simplifies the installation of Oracle R Distribution by automatically resolving RPM dependencies.

To install Oracle R Distribution on Oracle Linux 8 Using Dnf:

1. Log in to the Linux server as root and change to the /etc/yum.repos.d directory:

   cd /etc/yum.repos.d

2. For Oracle Linux 8, in addition to the Oracle Linux 8 main repository, the appstream, codereadybuilder, and addons repositories are required. As root, create the repository /etc/yum.repos.d/oracle-linux-ol8.repo and specify enabled=1 for ol8_baseos_latest, o18_appstream, o18_codereadybuilder and ol8_addons.

   The result looks similar to the following:

   [ol8_baseos_latest]
   name=Oracle Linux $releasever BaseOS ($basearch)
   baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/$basearch
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
   gpgcheck=1
   enabled=1
   
   [ol8_appstream]
   name=Oracle Linux $releasever Application Stream ($basearch)
   baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/appstream/$basearch
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
   gpgcheck=1
   enabled=1
   
   [ol8_codereadybuilder]
   name=Oracle Linux $releasever Code Ready Builder ($basearch)
   baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/codeready/builder/$basearch
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
   gpgcheck=1
   enabled=1
   
   [ol8_addons]
   name=Oracle Linux $releasever Add ons ($basearch)
   baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/addons/$basearch/
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
   gpgcheck=1
   enabled=1

3. As root, install R-4.0.5 for Linux 8 using the dnf command. Run the dnf command to install R.

   dnf install R-4.0.5
