`fa_IR.UTF-8` local is not installed by default. That's a bug!

I think ubiquity should generate the locale when Iran is selected.

Does it work once the locale is installed? what language did you select during the installation?

Which language did you select during the installation? Were you connected to internet from ubiquity?

I decided to English during the installation.

I think I was connected to the Internet but I'm not sure.

Yes. It worked when I installed the locale.

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.

the environment is at fault there, it's not a calendar bug, could be one in ubiquity though

Status changed to 'Confirmed' because the bug affects multiple users.

This bug also persisted in Ubuntu 20.10 with ubiquity 20.10.13

I also have this bug in the last daily build on all flavors.

The screen shot of the Language Support's problem in the last daily build of Xubuntu about this bug.

As you can see Azerbaijani is the default. Also Persian isn't exist.

I have this problem too!

Same here

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.

Changed file: d-i/patches/localechooser-post-base-installer.patch

Similar bugs for `German` and `Belgian`

Wrong language (German) after fresh install: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1295627

default locale when selecting english(US) and belgian timezone is incorrect: (https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1907914)

Prove this change will fix bug.

1. Boot system with live installer for example `xubuntu-21.04-desktop-amd64.iso`.
2. Fix file : `/usr/lib/ubiquity/localechooser/post-base-installer`
and add `IR) deflang=fa ;;`.
3. Run ubiquity

Run:
$ ubiquity -d gtk_ui --debug

Logs:
$ tail -f /var/log/syslog

See screenshot taken after install with this change to ubiquity installer.

I check this bug on Ubuntu 20.04, 21.10, 22.04 and Xubuntu 22.10
In first page of installer that we choose language if I select Persian language final locale `fa_IR` will set and after install complete.

I add default language for IRAN to ubiquity.

For a stable release update to 22.04, feel free to follow the procedure at

https://wiki.ubuntu.com/StableReleaseUpdates

to add the metadata to the bug such that it can be reproduced and resubscribe ubuntu-sponsors when that's done, I think the patch is trivial to adapt from the commit that it doesn't need a new debdiff.

This bug was fixed in the package ubiquity - 23.10.3
