apt-get install tzdata noninteractive
This is the script I used (Updated Version with input from @elquimista from the comments) #!/bin/bash ln -fs /usr/share/zoneinfo/America/New_York /etc/localtime DEBIAN_FRONTEND=noninteractive apt-get install -y tzdata dpkg-reconfigure –frontend noninteractive tzdata Seems to work fine. As one liner: DEBIAN_FRONTEND=noninteractive apt-get install -y –no-install-recommends tzdata
