Today our routine
docker build in our CI got stuck.
Setting up tzdata (2019c-3ubuntu1) ... debconf: unable to initialize frontend: Dialog debconf: (TERM is not set, so the dialog frontend is not usable.) debconf: falling back to frontend: Readline Configuring tzdata ------------------ Please select the geographic area in which you live. Subsequent configuration questions will narrow this down by presenting a list of cities, representing the time zones in which they are located. 1. Africa 4. Australia 7. Atlantic 10. Pacific 13. Etc 2. America 5. Arctic 8. EurJob Finished
The base image we used is
ubuntu:latest. But Ubuntu just released 20.04 Focal Fossa yesterday, and one of the changes there broke our builds.
Here are 2 options to go around fixing it:
#1 Change to ubuntu:18.04
Just change your base image down to an older stable version.
-FROM ubuntu:latest +FROM ubuntu:18.04
#2 DEBIAN_FRONTEND=noninteractive apt-get…
-RUN apt-get update && \ +RUN DEBIAN_FRONTEND=noninteractive \ + TZ=Asia/Singapore \ + apt-get update && apt-get install -y \
I don’t go for
ENV DEBIAN_FRONTEND=noninteractive because that’s not an env var I wanna set permanently for the container image.
Anyway that’s just a quick fix, I hope they patch it soon!
