Here are steps to install Oracle Linux 8 yum repository into Red Hat Enterprise Linux (RHEL) derivative or Fedora, in this case, it's AlmaLinux 8.
For RHEL 7 and its derivatives, you may refer to the post: How to Setup Oracle Linux 7 Yum Repository.
Edit Oracle Linux 8 Yum Repository
Here we edit a temporarily used yum repository for further operation.
[root@test ~]# cd /etc/yum.repos.d/
[root@test yum.repos.d]# vi public-yum-ol8.repo
[ol8_baseos_latest]
name=Oracle Linux 8 BaseOS Latest ($basearch)
baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/baseos/latest/$basearch/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
gpgcheck=1
enabled=1 The repository is enabled.
Download Oracle Linux 8 GPG Key
To prevent GPG key retrieval failed, we need to download the right GPG key for the above Oracle yum repository.
[root@test yum.repos.d]# wget https://yum.oracle.com/RPM-GPG-KEY-oracle-ol8 -O /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
Let's see what we have now.
[root@test yum.repos.d]# ll /etc/pki/rpm-gpg/
total 8
-rw-r--r--. 1 root root 3494 Nov 19 11:44 RPM-GPG-KEY-AlmaLinux
-rw-r--r--. 1 root root 3169 Jul 23 2019 RPM-GPG-KEY-oracle RPM-GPG-KEY-oracle has been downloaded at the right place.
Please note that, the target filename has been changed and different from the source.
Install Newest Oracle Linux 8 Public Yum Repository
To install the newest Oracle Software yum repository, we use command dnf to install oraclelinux-release-el8.
[root@test yum.repos.d]# dnf -y install oraclelinux-release-el8
Here we leave an informative release version for this OS.
[root@test yum.repos.d]# echo "Oracle Linux Server release 8.7" > /etc/oracle-release Remove Old Repository
Since the temporary repo file is no longer used, we can make it step aside.
[root@test yum.repos.d]# mv public-yum-ol8.repo public-yum-ol8.repo.disabled Optionally, we can remove old repositories and see what we have now.
[root@test yum.repos.d]# rm -f ./almalinux-*
[root@test yum.repos.d]# ll
total 16
-rw-r--r--. 1 root root 3660 Nov 9 00:55 oracle-linux-ol8.repo
-rw-r--r--. 1 root root 214 Jan 29 21:01 public-yum-ol8.repo.disabled
-rw-r--r--. 1 root root 941 Nov 10 10:43 uek-ol8.repo
-rw-r--r--. 1 root root 243 Nov 10 10:43 virt-ol8.repo Test New Repositories
