Re: [weewx-user] Failed to update 4.10.2 to 5.0.2 with setup.py old installation

[Tom Keffer]

You did not update your weewx service file, /etc/systemd/system/weewx.service. This is step #4 in the instructions.

Hello, I have weewx 4.10.2 installed via setup.py, and I followed the instructions at https://github.com/weewx/weewx/wiki/v5-upgrade but when trying to start the service I get this error:

Apr 10 07:39:51 raspberrypi systemd[1225]: weewx.service: Failed to locate executable /home/weewx/bin/weewxd: No such file or directory

Apr 10 07:39:51 raspberrypi systemd[1]: weewx.service: Failed with result 'exit-code'.

It is because in the instructions the bin has to be moved to bin.old, if I put the bin back it works, but with version 4.10.2. How can I update to version 5.0.2 and keep my old configuration? Thank you.

Thanks... but... step 4 done>

Check to see if you have multiple weewx.service files on your system.  It's possible you have one under /etc and a different one under /usr and systemd is using the old one.

If that is not the case, post your /etc/systemd/system/weewx.service file please.

So is there a /home/weewx/bin/weewxd file ?

What is in your /home/weewx tree ?

Did you perhaps install as user 'pi' and everything is under there ?

[Tom Keffer]

Juan, your service file, weewx.service, looks like the old V4.10 service file. The new V5.0 file has a few more entries.

Double check that you did step #2: upgrade the old examples and utility files.

I suspect this may be a permissions issue. What do you get for the following commands?

ls -l /home/weewx

ls -l /home/weewx/examples

Make sure everything in the directory "/home/weewx" is writable by user "pi". Usually, it's easiest just to have everything under /home/weewx owned by user "pi":

sudo chown -R pi:pi /home/weewx
