This bug was fixed in the package tzdata - 2024a-2ubuntu1 --------------- tzdata (2024a-2ubuntu1) noble; urgency=medium
* Merge with Debian unstable. Remaining changes: - Ship 2024a ICU timezone data which are utilized by PHP in tzdata-icu - Add autopkgtest test case for ICU timezone data - Do not rename NEWS into changelog.gz, this fixes a build failure on moment-timezone.js - Point Vcs-Browser/Git to Launchpad - generate_debconf_templates: Work around AttributeError on icu import tzdata (2024a-2) unstable; urgency=medium * Update Italian debconf translation. Thanks to Ceppo <ce...@oziosi.org> (Closes: #1063490) * Replace America/Godthab by America/Nuuk * Do not replace CET, CST6CDT, EET, EST*, HST, MET, MST*, PST8PDT, WET. The replacements differed in using daylight saving. (LP: #2055718) * Fix updating US/Indiana-Starke to America/Indiana/Knox * Allow ziguard.awk to generate timezone symlink that point to symlinks to fix (at least) the timezone symlinks Africa/Asmera, Antarctica/South_Pole, Iceland, Pacific/Ponape, and Pacific/Truk. * test_timezone_conversions: Check symlink targets -- Benjamin Drung <bdr...@ubuntu.com> Fri, 05 Apr 2024 22:32:21 +0200 ** Changed in: tzdata (Ubuntu) Status: Fix Committed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to tzdata in Ubuntu. https://bugs.launchpad.net/bugs/2055718 Title: timezone changed unexpectedly from EST to America/Adak or America/Indiana/Indianapolis Status in tzdata package in Ubuntu: Fix Released Status in tzdata source package in Focal: New Status in tzdata source package in Jammy: New Status in tzdata source package in Mantic: New Bug description: [ Impact ] On every tzdata package upgrade the configured timezone might be updated to an incorrect one. I enhanced debian/test_timezone_conversions to detect those inconsistencies and fixed everything that was found by this check. The SRUs contain a backport of the script from noble. [ Test Plan ] debian/test_timezone_conversions is enhanced to check the timezone conversions for consistency to prevent such kind of issues in the future. debian/test_timezone_conversions is run during built and as autopkgtest. In addition, manual check can be done. The following test should stay at `EST` (and not update to `America/Adak`): ``` ln -sf /usr/share/zoneinfo/EST /etc/localtime dpkg-reconfigure --frontend noninteractive tzdata ls -alh /etc/localtime ``` `US/East-Indiana` should be updated to `America/Indiana/Indianapolis` and not to `America/Adak`: ``` ln -sf /usr/share/zoneinfo/US/East-Indiana /etc/localtime dpkg-reconfigure --frontend noninteractive tzdata ``` `America/Louisville` should be updated to `America/Kentucky/Louisville` and not to `America/Adak`: ``` ln -sf /usr/share/zoneinfo/America/Louisville /etc/localtime dpkg-reconfigure --frontend noninteractive tzdata ``` [ Other Info ] The autopkgtest for chrony is flaky on jammy and newer (see bug #2002910). [ Regression potential ] The patch ziguard.awk-Move-link-to-link-feature-from-vanguard-to- ma.patch moves the link to link feature from vanguard to main dataform to produce correct symlinks. This results in symlinks that can point to symlinks. The zic from glibc that we use can handle that, but there might be other parsers that read /usr/share/zoneinfo/tzdata.zi directly and could fail to handle symlinks to symlinks. [ Original report ] A user reported this regression on https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/2052739: UPDATE: I don't think it's a regression anymore, see comment #5 """ Hello. After automatic upgrade of tzdata from 2023c-0ubuntu0.22.04.2 to 2024a-0ubuntu0.22.04 the previously set EST time zone was automatically changed to "America/Adak" or "America/Indiana/Indianapolis" on all our servers (50+). Look like a bug in tzdata configure script.
