OpenHABian 3.1 Set system locale - Error message

sl4m · August 20, 2021, 5:31pm

Dear all,

searching for a way to display the datetime days in German language I read that i have to set the system locale in sudo openhabian-config to German.

Setup:

Raspberry PI 3b+
OpenHABian 3.1
OpenHAB 3.1
openHABian Configuration Tool [stable]patchday-20210119-1118(b56733a)

So I went to: 30 System settings → 32 Set system locale

Selected the following line with Space and Enter

[*] de_DE.UTF-8 UTF-8

Then the following message showed up. I pushed Enter

Then i received the following error:

There was an error or interruption during the execution of:                  │
          │   "30 | System Settings"

This is the log-out put in the SSH terminal:

+ case "$choice2" in
+ locale_setting
+ local locale
+ dpkg -s locales
+ [[ -n 1 ]]
++ timestamp
++ date +%F_%T_%Z
+ echo -n '2021-08-20_19:22:06_CEST [openHABian] Setting locale based on user choice... '

+ return 1

When i check locale in the SSH terminal, this is the output:

openhabian@openhab:~ $ locale

LC_TELEPHONE="en_US.UTF-8"

I really dont know what to do. Can someone maybe give me a hint?
Thank you!

By doing this i am afraid i also destroyed something.
Because now i see the following in the main UI:

I supposed to be 22.6 °C.
Also i dont see German letters like Ä,Ö,Ü anymore

Dunno about your locale issue, but this

is bad.
The ‘stable’ branch of openHABian is for openHAB 2 and has not been updated in a long time.

Change to ‘openHAB’ or ‘main’ branch then see if that makes a difference for your issue.

sl4m · August 21, 2021, 11:09am

You are right.
I changed it to OpenHAB3 branch and did a reboot.
After this i tried again to set the locale in system settings.
However with the same result:

+ echo -n '2021-08-21_13:06:59_CEST [openHABian] Setting locale based on user choice... '

After this i do at least have °C again, however still no German letters and no translation to German weekday names:

I think I also had that problem but do not remember how I resolved it from the command line.

But it looks like there is a mixture of en_US for LANGUAGE and de_DE for LANG.
Could this be the problem ?

What is the content of /etc/default/locale ?

sl4m · August 21, 2021, 11:46am

It seems to be a big mess now …
Even if the mainUI shows the temperature unit °C correct the item value in the MQTT command is ?C.

Item 'HASP_demo_Plate_Command_JSON' predicted to become ['p10b52.text=17 ?C']

Same item in the Developer Sitemap:

{ "state": "16.93 °C", "displayState": "16.9 °C" }

Line of the rule:

 HASP_demo_Plate_Command_JSON.sendCommand("['p10b52.text=" + Wetter_Forecast_ForecastHours12_Temperature.state.format("%.0f °C") + "']")

At the start of the ssh terminal i also see this message at the top:

-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

/bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Content of /etc/default/locale is the following

#  File generated by update-locale
#LANG=en_US.UTF-8
LC_CTYPE=en_US.UTF-8
LC_ALL=en_US.UTF-8
LANGUAGE=en_US.UTF-8

Edit:
I now switched back to en_US.UTF-8 in the openhab-config.
(Deactivated de_DE.UTF-8 UTF-8 before).
Didnt receive any errors.
After a reboot I do have now correct temperature unit (°C) in mainUI and MQTT command again.
Also German letters are working again.
However, of course still english DateTime naming.

Wolfgang_S · August 21, 2021, 12:31pm

Region is set to Germany and language is set to german under settings ?

sl4m · August 21, 2021, 12:36pm

You are referring to the settings of the MainUI?
Yes MainUI Settings are set to German and Germany.

mstormi · August 21, 2021, 12:42pm

Uncomment LANG, too. Setting all of these to de_DE.UTF-8 should work.

If you want to reconfigure anything you can also run dpkg-reconfigure locales in CLI.

sl4m · August 22, 2021, 7:25am

You are right!
I adapted this file and set again the locale in the openhab config to German.
No errors and now its working fine!

Thank you alot!
