WeeWX 4.10.1 not updating web page graphics

[Paulo Reis]

Hi,

I am a WeeWX user for some time now (RPi with DietPi connect to a WH1080 weather station).

Yesterday, after updating to WeeWX version 4.10.1 (with Seasons 4.10.1 Skin) graphics from web page stopped updating. Other information present in web page is update apart from graphics (I check dates of graphic files and they are from time before update).

I have restarted my RPi several times, restarted weewx service and also my weather station, to no success.

Then I decided to check weewx service status (/etc/init.d/weewx status) and got following errors:

- - - - - - - - - - - - - - - - - - - -

Can you please help?

If any additional information is required, please ask.

Than you in advance.

No doubt you are running WeeWX under python 2 and have encountered the bug at issue #840. I am sure in time there will be a release that will fix this issue, but in the meantime you can replace the defective imagegenerator.py as follows:

1. delete the defective imagegenerator.py:

$ sudo rm /usr/share/weewx/weewx/imagegenerator.py

2. download the updated imagegenerator.py:

$ wget -P /usr/share/weewx/weewx https://raw.githubusercontent.com/weewx/weewx/master/bin/weewx/imagegenerator.py

note this command may require privileged access ie prefix the command with sudo

3. restart WeeWX

Hi, Gary.

Thank you very much for these instructions.

Already replaced imagegenerator.py with new version and got updated graphics.

Best regards,
