Comment 8 for bug 1891270

This one also affects me. As you can see in the attached picture during installation internet connection establish and `apt` connected to the `http://ir.archive.ubuntu.com/ focal main amd64`.

I select English for setup language but after that choose Tehran/IRAN as location.

I think locale not correctly set when select Tehran/IRAN in ubiquity.

This is what return from locale command.

$ locale

LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=az_IR
LC_TIME=az_IR
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=az_IR
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=az_IR
LC_NAME=az_IR
LC_ADDRESS=az_IR
LC_TELEPHONE=az_IR
LC_MEASUREMENT=az_IR
LC_IDENTIFICATION=az_IR
LC_ALL=

As @Danial Behzadi said, It should be `fa_IR UTF-8` as IRAN official language is Farsi/Persian not Azeri.
