Locale wrongly configured

Question

I have just launched an EC2 machine, in the frankfurt region. The locale is corrupted:

ubuntu@myhost:~$ locale
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=de_DE.UTF-8
LC_TIME=en_US.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=de_DE.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=de_DE.UTF-8
LC_NAME=de_DE.UTF-8
LC_ADDRESS=de_DE.UTF-8
LC_TELEPHONE=de_DE.UTF-8
LC_MEASUREMENT=de_DE.UTF-8
LC_IDENTIFICATION=de_DE.UTF-8
LC_ALL=

How can I correct the issue?

Answer 1

Edit /etc/locale.gen:

sudo vi /etc/locale.gen

And make sure that:

de_DE.UTF-8 UTF-8

is uncommented. Then just do:

sudo locale-gen

And verify:

$ cat /etc/locale.gen | grep -v '^#'
de_DE.UTF-8 UTF-8
en_US.UTF-8 UTF-8

$ locale -a
C
C.UTF-8
de_DE.utf8
en_US.utf8
POSIX
