I get this error each time I update the system using apt-get. What does this error mean? Any ideas on how to correct it? (I am running Ubuntu 11.10)

    The problem is apparently the lowercase "utf8". The "sudo update-locale LANG=en_US.UTF-8" should do the trick. – stolsvik Jun 29 '14 at 23:13
  • I want to add that I also get this "error" when the mysql service is disabled (if installed) while updating on Mint. After enabling it, the problem disappear. – not2qubit Nov 22 '17 at 16:56

Usually this error means that you could have been changing between different languages (locales) and something has caused this to error erroneously.

You could try regenerating your list of locales with

sudo dpkg-reconfigure locales

For me the result was:

Generating locales...
  en_AG.UTF-8... done
  en_AU.UTF-8... done
  en_BW.UTF-8... done
  en_CA.UTF-8... done
  en_DK.UTF-8... done
  en_GB.UTF-8... done
  en_HK.UTF-8... done
  en_IE.UTF-8... done
  en_IN.UTF-8... done
  en_NG.UTF-8... done
  en_NZ.UTF-8... done
  en_PH.UTF-8... done
  en_SG.UTF-8... done
  en_US.UTF-8... up-to-date
  en_ZA.UTF-8... done
  en_ZM.UTF-8... done
  en_ZW.UTF-8... done
Generation complete.

Then resetting your local locale with:

sudo update-locale LANG=en_US.UTF-8

i.e. use one of the Locale values in the output above

In my case, the problem was that /usr/share/initramfs-tools/hooks/root_locale is expecting to see individual locale directories in /usr/lib/locale but locale-gen is configured to generate an archive file by default.

I fixed it by running:

sudo locale-gen --purge --no-archive

    Per: man locale-gen Matt's explanation is correct, all locales are no longer in individual directories due to size limitations in libc. "locale-gen is a program that reads the file /etc/locale.gen and invokes localedef for the chosen localisation profiles." Warning: no support for locale: xx_XX.utf8 is fixed by his answer :) +1 – xtrchessreal Oct 31 '17 at 20:11

No support for locale: en_US.utf8.

This usually happens when installing the updates when it says the above

Solution is open a Terminal

By default you should have something that says

pai@ubuntu:~$

Where pai is the user name

Now once you are on the terminal You copy paste this line"

sudo dpkg-reconfigure locales

" The system will ask you for a password.

[sudo] password for pai:

As soon as you enter the password you get this

Generating locales...
  en_AG.UTF-8... up-to-date
  en_AU.UTF-8... up-to-date
  en_BW.UTF-8... up-to-date
  en_CA.UTF-8... up-to-date
  en_DK.UTF-8... up-to-date
  en_GB.UTF-8... up-to-date
  en_HK.UTF-8... up-to-date
  en_IE.UTF-8... up-to-date
  en_IN.UTF-8... up-to-date
  en_NG.UTF-8... up-to-date
  en_NZ.UTF-8... up-to-date
  en_PH.UTF-8... up-to-date
  en_SG.UTF-8... up-to-date
  en_US.UTF-8... up-to-date
  en_ZA.UTF-8... up-to-date
  en_ZM.UTF-8... up-to-date
  en_ZW.UTF-8... up-to-date
Generation complete.

Now copy paste this stuff below on the terminal again"

sudo update-locale LANG=en_US.UTF-8

"

That should take care of it....
