This is not the right answer.


"make allnoconfig; make bindeb-pkg"
failed on Ubuntu 16.04, but succeeded on Ubuntu 18.04

I am puzzled...

The docker file I used is below.

If I change "FROM ubuntu:16.04" to "FROM ubuntu:18.04",
it goes well.




------------------->8------------------
FROM ubuntu:16.04

# user name
ARG USER=foo

# packages to install
ARG PKGS=" \

RUN \
apt-get update && \
DEBCONF_NOWARNINGS=yes apt-get install -y apt-utils && \
apt-get install -y ${PKGS} && \
useradd -m ${USER} && \
echo "${USER} ALL=(ALL) NOPASSWD:ALL" >> /etc/sudoers
