Thank you for taking the time to report this bug and helping to make Ubuntu better.
Sadly dpkg terminal log is missing. So the information for further investigation is missing. Reinstalling tzdata (sudo apt install --reinstall tzdata) should solve the issue. I assume that has happened in the meantime and I am closing this bug. Please report back if you still experience it. ** Changed in: tzdata (Ubuntu) Status: New => Invalid -- 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/1604130 Title: package tzdata 2016f-0ubuntu0.16.04 failed to install/upgrade: Paket tzdata ist nicht bereit zur Konfiguration kann nicht konfiguriert werden (momentaner Status »half-installed«) Status in tzdata package in Ubuntu: Invalid Bug description: Problem appears when doing upgrades via "sudo apt upgrade".
