Installation problems

[Auchtermuchty Weather]

I'm trying to install the latest version, 5.1, onto a card for my test Pi.

I installed bookworm, had problems installing the package until I used the instructions in https://weewx.com/apt/.

Eventually I removed it with  sudo apt-get remove --purge weewx.

However there are still issues. This is what was displayed on the screen - -3.321637 is the station's longitude. And as you can see, the service isn't installed.

I suspect that you have a corrupted debconf database. Be sure that when you remove WeeWX, you use

  sudo apt purge weewx

There is no "--purge" flag.

To fix, try flushing the debconf database:

  sudo echo PURGE | debconf-communicate weewx

Then install again.

Yes that fixed it, thanks. I have no idea where the idea of using --purge came from, either there's a dodgy page out there or I misread one.
