Oracle Linux 10 Developer Preview can be installed with Secure Boot enabled in the UEFI firmware, but the system fails to load on first boot. This is because the UEK-next kernel is a Developer Preview feature and isn't signed with an Oracle UEFI certificate. You can test Oracle Linux 10 Developer Preview with Secure Boot disabled in the system firmware.

If you need to test with Secure Boot enabled, you can enroll the hash of the UEK-next kernel included in the Developer Preview into the Machine Owner Key (MOK) list. You can find out more about how to do this in the tutorial at Use mokutil to Update Signature Keys for UEFI Secure Boot.

When installing Oracle Linux 10 Developer Preview on a system that requires access to a network proxy, setting the installer to use the Closest Mirror option for a network-based install might fail even if the proxy service is configured in the installer.

Either use the full installation media to complete the installation, or configure proxy settings in the installer and manually add the BaseOS URL in the Software Selection. For example, for x86_64 platforms, set the installation URL to https://yum.oracle.com/repo/OracleLinux/OL10/baseos/developer/x86_64/, or https://yum.oracle.com/repo/OracleLinux/OL10/baseos/developer/aarch64/ for Arm platforms.

Installation onto some systems with NVMe devices might fail when using the default partitioning option in the installer. The installer errors out with the following message:

fsconfig system call failed: Structure needs cleaning

This issue is caused by an installer bug when handling XFS file systems.

To work around the issue, you can change the file system for the device to Ext4 in the installer before proceeding with the installation. You can do this either in the graphical installer or by using a kickstart configuration.
