Upgrade - how to determine the original install method

[Wiggytoo]

Hi - I am running weewx 3.9.1 and was planning to upgrade to 4.5.1.

I came across this in the documentation

"Warning!

You must use the same upgrade technique as your initial install! For example, if you used setup.py to install WeeWX, then you should use setup.py to upgrade. If you used a DEB or RPM package to install, then you should upgrade using the same package type."

I want to ensure I take this sound advice but I have no idea how I originally installed it, is there some way of telling this?

Many thanks,

Gavin

Simplest way is to look for where your weewx.conf is located.   If it's in /home/weewx then you used setup.py

Many thanks, it's in etc/weewx.

Also you can look at installed packages.

apt search weewx or apt list --installed | grep weewx

rpm -qa | grep weewx

Yes, but we have seen instances where people have installed both ways and are only running one currently.

Matthew reminded me a while back that the only way to know which one is 'running' is to look for the pathname of the weewxd that is currently running.   I'd do it by looking with the 'ps' command for the weewxd processs.

# this one is setup.py

root@debian:~# ps axu|grep weewxd|grep -v grep

root     13327 45.7 55.3 201136 68276 ?        Sl   Jun27 81488:50 /usr/local/bin/python3 /home/weewx/bin/weewxd --daemon --pidfile=/var/run/weewx.pid /home/weewx/weewx.conf

# this one is running the packaged weewx

[vince@pi4 ~]$ ps axu | grep weewxd|grep -v grep
