The issue you’re experiencing with the Chromium and Firefox browsers on your Jetson Orin NX device is related to SELinux (Security-Enhanced Linux) context and capability issues. Here’s a breakdown of the problem and potential solutions:
Error Analysis
The error messages indicate that the browsers are unable to create a user data directory due to failed verification of the SELinux context. Additionally, the matchpathcon executable is not found in the PATH, and the browsers are unable to set capabilities due to an “Operation not permitted” error.
SELinux Context
SELinux is a security feature that enforces mandatory access control (MAC) policies on Linux systems. It labels files, processes, and users with a specific context, which determines their access permissions. In this case, the browsers are unable to verify the SELinux context of the user data directory, which prevents them from creating the directory.
Capability Issues
Capabilities are a Linux feature that allows processes to perform specific actions without requiring root privileges. The browsers are unable to set capabilities due to an “Operation not permitted” error, which suggests that the system is not allowing the browsers to acquire the necessary capabilities.
Comparison with Other Jetson Devices
The issue you’re experiencing is specific to the Jetson Orin NX device. Other Jetson devices, such as the Jetson AGX Orin, may not exhibit this behavior. However, it’s essential to note that the Jetson Orin NX is a more recent device, and its security features might be more restrictive than those of older devices.
Potential Solutions
- Disable SELinux: You can try disabling SELinux to see if it resolves the issue. However, please note that disabling SELinux may compromise the security of your system. To disable SELinux, you can edit the
/etc/selinux/config file and set SELINUX=disabled.
- Update SELinux Policies: Ensure that your SELinux policies are up-to-date. You can update the policies by running the
sudo apt-get update and sudo apt-get install selinux-policy commands.
- Set Correct SELinux Context: Verify that the SELinux context of the user data directory is set correctly. You can use the
ls -Z command to check the SELinux context of the directory.
- Grant Capabilities: Grant the necessary capabilities to the browsers. You can use the
sudo setcap command to grant capabilities. For example, to grant the CAP_NET_BIND_SERVICE capability to the Chromium browser, you can run the sudo setcap CAP_NET_BIND_SERVICE=+ep /usr/bin/chromium command.
- Reinstall Browsers: Try reinstalling the browsers to see if it resolves the issue.
Conclusion
The issue you’re experiencing with the Chromium and Firefox browsers on your Jetson Orin NX device is related to SELinux context and capability issues. By disabling SELinux, updating SELinux policies, setting the correct SELinux context, granting capabilities, or reinstalling the browsers, you may be able to resolve the issue. However, please note that these solutions may have security implications, and you should carefully evaluate the risks before implementing them.
