Locale issues - can't start nextcloud

iā€™ve been trying to install NextCloud on Arch Linux but iā€™m stuck at the point of starting it up.

i keep getting this error

Setting locale to en_US.UTF-8/fr_FR.UTF-8/es_ES.UTF-8/de_DE.UTF-8/ru_RU.UTF-8/pt_BR.UTF-8/it_IT.UTF-8/ja_JP.UTF-8/zh_CN.UTF-8 failed
Please install one of these locales on your system and restart your webserver.

Iā€™ve tried a few things including setting my php-intl settings

`extension=intl
[intl]

intl.default_locale = en_AU.utf8`

this seems to be running from phpinfo

i have also set in config/config.php
<?php
$CONFIG = array (
ā€˜instanceidā€™ => ā€˜ocr53y11k5kiā€™,
ā€˜default_localeā€™ => ā€˜en_AUā€™,
ā€œforce_localeā€ => ā€œen_AUā€,
);

iā€™m not sure what to try next.

ok, so i canā€™t use en_AU.utf8 ?
am i the only skip here?
i changed it to en_US and it seems to work now.

You have to install it on your Linux system, here from the archlinux docs: https://wiki.archlinux.org/index.php/locale
