This one also affects me. As you can see in the attached picture during installation internet connection stablished and `apt` connetcted 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. ** Attachment added: "Internet connection while ubuntu 20.04 installation" https://bugs.launchpad.net/ubuntu/+source/gnome-calendar/+bug/1891270/+attachment/5411670/+files/ubuntu.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-calendar in Ubuntu. https://bugs.launchpad.net/bugs/1891270 Title: Iranian calendar shows in Azerbaijani language To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-calendar/+bug/1891270/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
