debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline

tzdata 2025b release

Fix Released

Bug description:
[ Impact ]
The 2025b release contains the following changes:
* New America/Coyhaique zone for Aysén Region in Chile, which moves
from -04/-03 to -03. It will not change its clocks on 2025-04-05.
* Improve historical data for Iran
[ Test Plan ]
Test cases were added to the autopkgtest to cover the testing:
* python: test_2025b
So the test plan is to check that the autopkgtest succeeds. Since
https://launchpad.net/bugs/207604 hasn't been backported to focal, we
need to test focal manually:
* dpkg-reconfigure tzdata
* Select America/Coyhaique
* This zone should be available
[ Other Info ]
* The autopkgtest for chrony is flaky on jammy and newer (see bug #2002910).
* The oracular autopkgtest needs to use exchange-calendars/4.5.5-2ubuntu0.1
* The focal autopkgtest needs to use postgresql-12/12.22-0ubuntu0.20.04.3
