It was all going so well....I did as you suggested - first copied all my
old weewx files to a USB drive on the Pi, bought a new SD card, installed
the latest Raspbian OS (Bookworm) and got my shiny new SD card running
fine. I then installed weewx and it started weewx up as expected and began
populating the empty database from 4 Sept on. Then I tried to stop weewx
so I could copy across the old database with all my history from 2016
onwards. For some bizarre reason I couldn't get the stop command to work,
as per below extract:
xxxxx@weatherpi:/etc $ sudo /etc/init.d/weewx stop
sudo: /etc/init.d/weewx: command not found
Am I being dumb? Any reason why this shouldn't work?
Thanks
David.
