We have two option for IRAN in `/usr/share/i18n/SUPPORTED` file. As `az_IR` comes first, installer use it instead of correct one fa_IR.
$ grep IR /usr/share/i18n/SUPPORTED az_IR UTF-8 fa_IR UTF-8 IRAN default language is Farsi/Persian . I add a default option for IRAN, i.e `IR -> fa_IR` to correct this issue.
