Upgraded OS to Ubuntu 24.04.1 LTS causes error by Belchertown skin?

[Stefan Gliessmann]

Dear All -

I just finished upgrading my weewx server's OS from Ubuntu 24.04. to Ubuntu 24.04.01 LTS.

After the reboot, things booted up just fine.

But no new reports were generated.

Going to the logfile, I found:

I read that the upgrade might have changed the installed modules of python3.

Is this really the root cause of this error message? And if so,  how do I fix it? Re-install the belchertown skin?

Anybodyelse did the Ubuntu upgrade recently?

I guess you may want to re-install some Python modules. The error message reports an error regarding the "locale" module. I see no connection to the Belchertown skin itself.

[Stefan Gliessmann]

Thank you Tom!

I need to improve my search skills in this group!

Cheers,

Stefan

Actually, the updated belchertown.py (three months ago) is already in place on my server.

Please notice that this is Ubuntu 24.04.01

Before the upgrade, it was running just fine on Ubuntu 24.04.

I did re-install "locales" already:

sudo apt-get update
sudo apt-get install --reinstall locales

A little test script return the correct format, too:

import locale
locale.setlocale(locale.LC_ALL, '')

print(locale.format_string("%g", 12345.6789, grouping=True))

 Hmm ...

[Stefan Gliessmann]

well - I just did another:

sudo wget https://github.com/poblabs/weewx-belchertown/raw/master/bin/user/belchertown.py

and now, it works ....

Thank you, again, Tom!

[Karen K]

Could you report what was the difference between the belchertown.py that created the error and the belchertown.py that works?

[Stefan Gliessmann]

I wish, I could :(

I needed to do a fresh install of my home station on June 23 from scratch.

And belchertown.py was last changed on Jun 21. (specifically for this issue).

So, I am really puzzled what was the issue ...
