Package: tzdata Version: 2024a-0+deb12u1 Severity: minor X-Debbugs-Cc: satw...@disjoint.net
Dear Maintainer, When installing the tzdata and debconf tries to ask questions and fails because stdin is not available, the package writes "/UTC" to /etc/timezone, which doesn't seem to be valid (note the leading slash). I would expect it to write either "Etc/UTC" or "UTC". This can happen, for example, during docker builds. (Example: https://github.com/docker-library/buildpack-deps/issues/161) It's easy to fix by setting DEBIAN_FRONTEND=noninteractive during install, but it seems like tzdata should still be able to write the correct default value to /etc/timezone in this situation.
