systemctl INVALIDARGUMENT

[Lucas Heijst]

After the update of weewx 5.0.0.a25 (or other a.. versions) to version 5.0.0.b1 with:
python3 -m pip install weewx --upgrade --user
Weewx won't run anymore

All instances of weewx got the same error when started with:
systemctl restart weewx_xxxx

May 25 18:35:02 pi35 systemd[1]: Started weewx xxxx.

Where did  weewx_xxxx.service come from? What's inside it?

'xxxx' stands for cmon, wbx1, rtld, and so on. each weewx instance has it's own systemctl files and weewx_xxxxx.conf settings

Additional data

systemctl was configured as follows for weewx v5.0.0.a20:

====

Create daemon voor rtld

cd ~/weewx-data

cp util/systemd/weewx_rtld.service /etc/systemd/system

chmod -wx /etc/systemd/system/weewx_rtld.service

systemctl daemon-reload

systemctl enable weewx_rtld

Start weewx_rtld

systemctl restart weewx_rtld

====

After each update of v 5.0.0axx with 

python3 -m pip install weewx --upgrade --user

weewx could be started, restarted and stopped with commands like

systemctl start weewx_rtld, systemctl restart weewx_rtld, systemctl stop weewx_rtld

After an update from version 5.0.0a23/24/25 to 5.0.0b1 I got the error as described above.

I think I found the cause of the error.

The location of my weewxd.py is in 

./usr/local/lib/python3.9/dist-packages/weewxd.py

Where the startup file expects it in

./usr/local/lib/python3.9/site-packages/weewxd.py

I quess somehow a symbolic link earlier was present which pointed to the right source

Workaround

I changed in files weewx_'xxxx'.service the path of weewxd.py as follows:
/root/.local/lib/python3.9/site-packages/weewxd.py
into:
./usr/local/lib/python3.9/dist-packages/weewxd.py

Now weewx starts ok with command
systemctl restart weewx_'xxxx'

Probably I did something wrong with the update of weewx

Usually executables show up in ~/.local/lib/python3.VV/site-packages. 

Definitely not "./usr/local/lib". Where did the leading "./" come from? 

If that "./" was a typo mistake, pip3 often puts things in /usr/local/lib/python3.VV/dist-packages if you do a "sudo" install (not recommended).

I logged in as user wx, then switched to user root and changed dir to / and searched for file weewxd.py 

wx@pi35:~ $ sudo su
root@pi35:/home/wx# cd /
root@pi35:/# find -name weewxd.py
./usr/local/lib/python3.9/dist-packages/weewxd.py
