Running updates on neo2 breaks wlanpi-webui

[mir2323]

Dear Developer,

I am currently facing an issue with the Gunicorn service while attempting to start the wlanpi-webui application. The error message I receive is as follows:

Aug 05 19:03:13 wlanpi systemd[1]: Starting Gunicorn daemon to serve wlanpi-webui...
Aug 05 19:03:13 wlanpi gunicorn[5048]: Traceback (most recent call last):
Aug 05 19:03:13 wlanpi gunicorn[5048]:   File "/opt/wlanpi-webui/bin/gunicorn", line 5, in <module>
Aug 05 19:03:13 wlanpi gunicorn[5048]:     from gunicorn.app.wsgiapp import run
Aug 05 19:03:13 wlanpi gunicorn[5048]: ModuleNotFoundError: No module named 'gunicorn'
Aug 05 19:03:13 wlanpi systemd[1]: wlanpi-webui.service: Main process exited, code=exited, status=1/FAILURE
Aug 05 19:03:13 wlanpi systemd[1]: wlanpi-webui.service: Failed with result 'exit-code'.
Aug 05 19:03:13 wlanpi systemd[1]: Failed to start Gunicorn daemon to serve wlanpi-webui.

It appears that the Python module 'gunicorn' is not being found when the Gunicorn service is started. I have already attempted to install the 'gunicorn' module, but the issue persists.

Could you please investigate this matter further and provide a solution to help me start the Gunicorn service successfully for the wlanpi-webui application?

Thank you for your prompt attention to this matter. I greatly appreciate your expertise and look forward to your assistance.

Best regards
Mirwaiss

Hi Mirwaiss, which WLAN Pi platform are you on?

Hi Josh,

Thank you for your reply. Well, I'm using the NanoPi Neo2 and I have the same issue with the Nanopi Neo. After running the 'sudo apt upgrade' command, everything seems to work, except for the 'wlanpi-webui.service' which isn't functioning.

Best regards
Mirwaiss

A fresh install of wlanpi-neo2-v2.1.3-231111, then an update of all packages where wlanpi-webui 1.0.0-b3-2 updates to 1.0.2b4 and the problem appears. I tried to downgrade wlanpi-webui, but that didn't solve the problem.

Hi. Is there any update regarding this issue? It's still happening on wlanpi-neo2-v2.1.5-240410, exactly like @mir2323 and @michal-ambroziak mentioned.

This is a known issue on the NEO2 platform. Unfortunately, I currently don't have the time or capacity to work on this issue. If you're interested in contributing a fix, I would be happy to review a pull request or assist where I can.

Same problem here.
Yes - I bought a NEO from Aliexpress to make my first steps with wlanpi - considering future upgrade to newer hardware.
Problem description:
Installed wlanpi-neo-v2.1.5-240411.img
System boots fine. Can login.
Trying to update via web UI - result is error message regarding Gunicorn.
Tried sudo apt get update and sudo apt get upgrade
Resulting in error message regarding not being able to create a symlink for /etc/nginx/sites-enabled/wlanpi_webui.conf
In another attempt the same message appeared for /etc/nginx/sites-enabled/wlanpi_speedtest.conf
Tried to sudo rm both files and running sudo apt install wlanpi-webui - but without success.
My prime objective is to be able to install updates on the wlanpi without bricking it.
Thanks for looking into it.

@ogermer thanks for letting us know. We'll try to get to the bottom of this so that at least the webui isn't broken, but can't promise feature enhancements.
