Issue Overview

Users have reported persistent notifications regarding the "nvidia-l4t-bootloader post install notification" message on the Nvidia Jetson Orin Nano Dev board. This issue occurs primarily after a fresh installation of JetPack 6.0 via the SDK Manager, where users experience the notification repeatedly upon booting their device.

The symptoms include:

• An update notification that appears on every boot, indicating that a reboot is required due to the "nvidia-l4t-bootloader" package.
• Users have noted that this is a recurring issue, indicating a lack of resolution after initial attempts to clear it.

Relevant specifications include:

• Operating System: JetPack 6.0 (Developer Preview)
• Installation Method: SDK Manager

The frequency of the issue is consistent, occurring on every boot, which significantly impacts user experience by causing unnecessary interruptions and confusion regarding system updates.

Possible Causes

Several potential causes for this issue have been identified:

• Software Bugs or Conflicts: As JetPack 6.0 is a developer preview, it may contain unresolved bugs that lead to persistent notifications.

• Configuration Errors: Improper configurations during installation may lead to the system incorrectly believing that a reboot is necessary.

• Driver Issues: The "nvidia-l4t-bootloader" notification may indicate problems related to driver installations or updates not being properly recognized by the system.

• User Errors or Misconfigurations: Users may inadvertently misconfigure settings related to update notifications or system reboots.

Each of these causes could contribute to the observed problem by preventing the system from correctly processing update requirements or clearing notifications.
