Error: bwrap: Can't mount proc on /newroot/proc and ldconfig failed when running QGroundControl via Flatpak on Jetson Nano B01

[asifpatankar]

System Configuration:

• Device: Jetson Nano B01
• OS: Ubuntu 18.04/20.04 (ARM64)
• QGroundControl Version: Installed via Flatpak from thopiekar.eu
• Flatpak Version: 1.12.4 or later

Issue:
After installing QGroundControl via Flatpak on my Jetson Nano B01, I receive the following error when trying to run the application:

bwrap: Can't mount proc on /newroot/proc: Device or resource busy
error: ldconfig failed, exit status 256

The full command used was:

flatpak run --device=all org.mavlink.qgroundcontrol

Steps Taken:

1. Rebooted the system to free up the /proc resource.
2. Attempted running with additional flags --nosocket=system-bus and --nosocket=session-bus.

Expected Outcome:
QGroundControl should run without issues on Jetson Nano, allowing access to hardware like serial ports for drone control.

Actual Outcome:
The application fails to run with the bwrap and ldconfig errors mentioned above.

Request:
Could this be an issue specific to the ARM64 architecture or Flatpak's sandboxing on Jetson devices? Any guidance on resolving or debugging this further would be appreciated.

Thank you!

Thank you for sharing your detailed system configuration and the issue you're facing. The error seems related to how Flatpak handles sandboxing and device access on ARM64 devices like the Jetson Nano.

Here are a few suggestions you can try:

• Run with relaxed Flatpak sandboxing:

  flatpak run --filesystem=host --device=all org.mavlink.qgroundcontrol

• Make sure Flatpak is updated with:

  sudo apt update && sudo apt upgrade flatpak

• Consider building QGroundControl natively if sandboxing continues to cause issues.

Let me know if this helps!
