Python locale error: unsupported locale setting

Python locale error: unsupported locale setting

Run following commands

export LC_ALL=en_US.UTF-8
export LC_CTYPE=en_US.UTF-8
sudo dpkg-reconfigure locales

It will solve this.

Make sure to match the .UTF-8 part to the actual syntax found in the output of locale -a e.g. .utf8 on some systems.

According to this link, it solved by entering this command:

export LC_ALL=C

You probably do not have any de_DE locale available.

You can view a list of available locales with the locale -a command.
For example, on my machine:

$ locale -a
C
C.UTF-8
en_AG
en_AG.utf8
en_AU.utf8
en_BW.utf8
en_CA.utf8
en_DK.utf8
en_GB.utf8
en_HK.utf8
en_IE.utf8
en_IN
en_IN.utf8
en_NG
en_NG.utf8
en_NZ.utf8
en_PH.utf8
en_SG.utf8
en_US.utf8
en_ZA.utf8
en_ZM
en_ZM.utf8
en_ZW.utf8
it_CH.utf8
it_IT.utf8
POSIX

Note that if you want to set the locale to it_IT you must also specify the .utf8:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, it_IT)   # error!
Traceback (most recent call last):
  File <stdin>, line 1, in <module>
  File /usr/lib/python2.7/locale.py, line 539, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting
>>> locale.setlocale(locale.LC_ALL, it_IT.utf8)
it_IT.utf8

To install a new locale use:

sudo apt-get install language-pack-id

where id is the language code (taken from here)

After you have installed the locale you should follow Julien Palard advice and reconfigure the locales with:

sudo dpkg-reconfigure locales
