(“That exists? en_DE?”)
Appearently, yes. I didn’t write it in there myself though, the installer / locale-gen
did. But as far as I got it, that shouldn’t be an issue, just tells applications that I want English language but am in Germany.
Some more outputs:
Listing enabled locales:
$ cat /etc/locale.gen | grep -v '^#'
en_US.UTF-8 UTF-8
de_DE.UTF-8 UTF-8
Full output of locale-gen
$ sudo locale-gen
Generating locales...
en_US.UTF-8... done
de_DE.UTF-8... done
Generation complete.
