Oracle Linux: Resolving Missing Repositories During Oracle Linux 7 to 8 Upgrade Using Leapp

Applies to:

Linux OS - Version Oracle Linux 7.9

Linux x86-64

Symptoms:

After running the `leapp preupgrade --oci` command, the following errors and inhibitors appear in `/var/log/leapp/leapp-report.txt`:

Risk Factor: high (error)
Title: Could not check for valid GPG keys
Summary: {"details": "No UsedTargetRepositories facts"}
Risk Factor: high (inhibitor)
Title: There are no enabled target repositories
Summary: This can happen when no custom repositories have been passed on the command line

These errors prevent the upgrade process from proceeding.

Cause:

The errors occur because the required Oracle Linux 8 repositories are not configured in the `/etc/yum.repos.d/` directory. Without these repositories, Leapp cannot fetch the necessary packages or metadata for the upgrade.
