Weewx is trying to create its own user directory. In my setup all the file which go into the html page are stored there. It does not have adequate permissions to create that directory.
I am not familiar with Raspberry PI, so I wasn't sure how to add this user. I did find this online.... http://raspi.tv/2012/how-to-create-a-new-user-on-raspberry-pi -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
