I didn't get an answer but I wasn't doing anything and this is an interesting topic. In Ubuntu 12.04, when opening a file in gedit or if I am working on the command line in dpkg, I get returned the error "locale not supported, falling back to default "C" libraries", and the one below,
Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
First make sure your library language is installed
sudo apt-get install language-pack-en-base,
for example.
Then, as superuser, shorten the work by allowing Ubuntu to automatically configure them:
sudo dpkg-reconfigure locales
Check your setup, if it's correct then good. But if you have the LANG= or LANGUAGE= settings blank, run this in command line:
locale -a
Which generates the locales installed and available to you.
Choose the locale from the output generated that fits your situation, and export that setting to replace your locales, for example:
export LC_ALL="en.utf-8"
For manual installation use export to set locale by hand which will manually install custom locales, first run the set up as above.
Then, say you want to install "en_us-8" for language but have need for another locale for NUMERIC and TIME, you may wish to use "en_NZ.utf-8" (remember: these are case-sensitive) or LANGUAGE="en_GB.utf-8" and NUMERIC="en.dk.ISO-8859-15". Traveling to New Zealand, I could change the locale LANGUAGE="en.NZ". For Germany, I would just need to install the locales pkg for it and input, in terminal, like the examples below:
export LC_ALL="en_US"
export LANG="en_US"
export LANGUAGE="en_NZ"
export C_CTYPE="en_US"
export LC_NUMERIC=
export LC_TIME=en"en_US"
LC_ALL= may remain empty.
This occurred to me more than once, on my mint mate 18, which is based on Ubuntu 16.04, so I'd like to share the solution I found, in case anyone needs.
Steps:
(These steps works for mint mate, but Ubuntu might have similar configurations, not sure)
Language and Region, make sure the default language for them are proper, e.g set to "English, United States UTF-8",first:
sudo apt-get purge locales
then:
sudo aptitude install locales
and the famous:
sudo dpkg-reconfigure locales
This rids the system of locales, then re-installs locales and downgrades libc6 from 2.19 to 2.13 which is the issue. Then configures locales again.
$ mkdir -p $HOME/.locale
$ I18NPATH=./wrk/ localedef -f UTF-8 -i fi_SE $HOME/.locale/fi_SE.UTF-8
$ LOCPATH=$HOME/.locale LC_ALL=fi_SE.UTF-8 date
$ echo "export LOCPATH=\$HOME/.locale" >> $HOME/.bashrc
$ echo "export LANG=fi_SE.UTF-8" >> $HOME/.bashrc
fi_SE to your LOCALE, and see UTF-8 or utf8
it just worked right for me by going to gnome-terminal and typing the command apt --fix locales and reboot your linux and your wait for the terminal error is over.it would be on your monitor this time for sure.
I managed to cause this myself when migrating home directory dot files to a new machine, and I failed to identify the cause for a while on account of searching files for LC_ but not LOC.
The ~/.bashrc file I copied had the following:
export LOCPATH=/var/guix/profiles/per-user/root/guix-profile/lib/locale
(the particular value here was on account of prior experiments with GNU Guix on the old machine; but the relevant fact is simply that the environment variable was set to a now-invalid path.)
This resulted in the following error when running various programs:
Warning: locale not supported by C library, locale unchanged
And these errors when running locale:
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
Removing (or commenting out) the LOCPATH line resolved my issues.
In my case,
sudo apt-get install language-pack-en-base
sudo dpkg-reconfigure locales
LANGUAGE=en_US:en
psppire
With locales you must remove the language that conflicts with your system, this worked for me, on ubunty kylin 16.04, I have installed it over ubuntu 14.04
