Known Issues and Usage Caveats

Refer to this page for issues specific to using eLxr. If you find an issue yourself not identified by the eLxr Test team, you can report it yourself at https://gitlab.com/elxr. Issues are repository specific, so navigate to the repository where the issue was found, then select Issues > New Issue.

  • Hyper-V Support in Microsoft Windows

    You may encounter the following error when installing the eLxr 12 Server image using Hyper-V’s Quick Create feature:

    ../../_images/hyper-v_fail.png

    To resolve this, you must deselect the option for Secure Boot when you initially create the VM, for example:

    ../../_images/hyper-v-disable-secure-boot.png

  • The create_default_user.sh script used when adding graphics support to NVIDIA Jetson Orin hardware requires Ubuntu version 20.04 or 22.04 to work successfully.

  • Intel x86 ISO images with OSTree require that the device and eLxr image be set up initially to support Secure Boot. For details, see eLxr 12 Quick Start: Enabling Secure Boot in eLxr 12.

  • AppArmor audit messages appear during system startup

    If you receive the following messages during startup, they are not actual system audit issues, and are instead harmless log information provided by AppArmor. You can safely ignore these messages.
