FTP Upload error (permission error)

[Marco P. Ferrara]

Hi there,

I have a Raspberry Pi (named pi-radar) with weewx 5.1.0 with python3 that receives data though Interceptor on a ecowitt protocol, generates pages with the Belchertown skin and then should FTP to an external server.

I have the following error that drops out:

When I run the reports manually they get uploaded correctly. Any idea what could generate the issue?

Thanks!

I would guess that, for some reason, the file /var/www/html/weewx/#FTP.last was protected. Perhaps weewx was run as root, but now you're running it as a non-root user? 

Try deleting it:

sudo rm /var/www/html/#FTP.last

It's used only to optimize the FTP transfer. It will be regenerated at the next reporting cycle.

And to clarify, the reports gets generated correctly, it is the FTP that fails.

Yup, that solved the issue, thank you.
