[Error] Preferred lanugage no permission denied

[Kisiekx]

When installing via ./install.sh choosing language is impossible (?). I tried using sudo ./install.sh but: "error: This script shouldn't be run as root."

Logs:

Enter your preferred language (en sr es ar de): en
sed: couldn't open temporary file /var/www/wx/sed6Xspk5: Permission denied
