Failed re-Installation

[Stephen Rogers]

I am currently unable to install  weewx on my Pi4 running Raspbian Buster.  I removed and purged the prior install since I wanted to start fresh, having had various issues along the way.

Here is the current status:

● weewx.service - weewx weather system
   Loaded: loaded (/etc/systemd/system/weewx.service; enabled; vendor preset: enabled)

I can see from the logs that weewx thinks the binary weewxd is located in /home/weewx/bin/.  this isn't right is it?

Did you perhaps install the second time using the dpkg (not setup.py) method ?

If you used setup.py, did you skip doing a 'sudo python3 setup.py install' after the 'python3 setup.py build' step ?

The locations of stuff differs depending on which way you installed things.  Where things are located is in the User's Guide (link)

Hmmm.  I just followed the directions on this page: https://weewx.com/docs/debian.htm, which says it is for installing on Debian systems.

OK I need to go to Installation using setup.py it looks like.  I found that page here: https://weewx.com/docs/setup.htm.  What are these other instructions above?  

[Stephen Rogers]

OK, using the setup.py method, all seems well.  I was using the other method and it did not work per my first message.

Regarding my attempt to use Ubuntu,  in the other thread, the failure I referred to was evidently Ubuntu crashing and corrupting ability to boot.  I simply re-used my Raspbian SD and started over with WeeWx using the same Pi4.  Now up and running.  Whew.

You're overthinking.  Pick a method (dpkg or setup.py) and stick with it.  It's that easy.

I now have WeeWx  running on Pi4 / Raspbian, and for the first time am using RSYNC to push the HTML report to cloud hosting instead of FTP, which was my goal.

The SSH key authentication required for RSYNC was tricky for me, partly because I use Windows for development and Linux for both WeeWx and for the cloud hosting.  Subtleties lurk about. Here is a very nice video that helped me get through it: https://www.youtube.com/watch?v=33dEcCKGBO4  

Since WeeWx normally runs as root SSH keys have to be installed under the root user on the WeeWx host.

With systemd, running as a non-root user is very easy. See the wiki article on running WeeWX under systemd:
