docker build时出现错误"debconf: unable to initialize frontend: Dialog"如何处理?
1. 详细日志如下:
debconf: unable to initialize frontend: Dialog
debconf: (Dialog frontend will not work on a dumb terminal, an emacs shell buffer, or without a controlling terminal.)
debconf: falling back to frontend: Readline
debconf: unable to initialize frontend: Readline
debconf: (This frontend requires a controlling tty.)
debconf: falling back to frontend: Teletype
dpkg-preconfigure: unable to re-open stdin:
2. 修复示例如下:
修改Dockerfile文件,
FROM ubuntu ARG DEBIAN_FRONTEND=noninteractive RUN apt-get update && \ apt-get -y install sudo dialog apt-utils RUN echo 'debconf debconf/frontend select Noninteractive' | debconf-set-selections
