Locale not supported by C library
 

When I open gedit and also some other applications, I get this message:

(gedit:29595): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.

Why is this happening and should I worry about it? It does not seem to affect my subsequent work.

Hi,

welcome to LQ!

What distro are you using? What is your current locale? What did
you choose during installation?

I am using Ubuntu 8.04. I have some pretty complex networking and don't dare upgrade because I do not know how to make that work!

When I type 'locale' at the prompt this is what I get:

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
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=


I very much appreciate being helped to help myself!

Can you verify whether 'language-pack-en-base' is installed?
If it's not - install it please, and then try:
dpkg-reconfigure locales

No, it is not installed but when I try to mark it for installation I get the following message:

Could not mark all packages for installation of upgrade
The following packages have unresolvable dependencies. Make sure that all requires repositories are added and enabled in the preferences.

language-pack-en-base:

Depends: language-pack-en but it is not going to be installed

Sigh..... What next?

Thank you so much!

Please please help!

At this stage I'll recommend that you locate & download those packages
manually from a close-by mirror and manually install them using dpkg.

Hi Tink,

A kind soul here helped me solve the problem. It just required uninstalling language-pack-en and reinstalling it. All now is well.

Thanks,
KL

Awesome - and well done.

I realize this thread is old but had to say thanks to @Tinkster and hopefully make his answer easier to find in the search engines. Out of all of the latest "solutions" I tried over the last couple of hours this 3 year old post fixed it for me.

Thank you sir!

SOLVED: Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale

LOCPATH environment variable
 

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_ and not LOC.

The ~/.bashrc file I copied had the following:

(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:

And these errors when running 'locale':

Removing (or commenting out) the 'LOCPATH' line resolved my issues.
