Today iana released timezone db update for 2020b version. Java's tzupdater tool (2.3.1) from oracle fails to patch OpenJDK8u265.

$ java -jar tzupdater.jar -v -u -f -l file:tzdata-latest.tar.gz
Using file:tzdata-latest.tar.gz as source for tzdata bundle.
java.home: /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre
java.vendor: AdoptOpenJDK
java.version: 1.8.0_265
tzupdater version 2.3.1-b02
JRE tzdata version: tzdata2020a
Downloaded file to /var/folders/k4/d4wwf5sd71b0hnp7lvrv1wk40000gn/T/tz.tmp_6/tzdata.tar.gz
tzupdater tool would update with tzdata version: tzdata2020b
Source directory does not contain source file: pacificnew
$ echo $?
1

with 2020c update

tzupdater tool would update with tzdata version: tzdata2020c
Source directory does not contain source file: africa

Update

This was recognized as a bug by Oracle https://bugs.openjdk.java.net/browse/JDK-8255747 and it is fixed as part of tzupdater release 2.3.2 - still waiting for the release to be published.

We had the same issue, we used to use the https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz URL and they apparently deployed a new version recently.

Quick fix: Try to use the previous version: https://data.iana.org/time-zones/releases/tzdata2020a.tar.gz :)

  • Thanks! What is the sha256 hash for the package that worked for you ? `$sha256sum tzdata-latest.tar.gz.4 9b053f951d245ce89d850b96ee4711d82d833559b1fc96ba19f90bc4d745e809 tzdata-latest.tar.gz.4` This still fails – jmj Oct 08 '20 at 05:02

A workaround if you need the updates is to take the file pacificnew from the tarfile tzdata2020a.tar.gz and add it to the tar file you want to use.

Update Timezone Updater 2.3.2 was released today
