The debdiff for focal is similar to the debdiff for jammy. Only debian/test_timezone_conversions needed some modification to work with the older Python version.
** Patch added: "tzdata_2024a-0ubuntu0.20.04.1.debdiff" https://bugs.launchpad.net/ubuntu/+source/tzdata/+bug/2055718/+attachment/5761753/+files/tzdata_2024a-0ubuntu0.20.04.1.debdiff ** Description changed: + [ 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.
