installing `lightdm` in Dockerfile raises interactive keyboard layout menu
11,939
Solution 1
This should work:
DEBIAN_FRONTEND=noninteractive apt-get install lightdm -y
I had the same problem installing CUDA and this fixed it.
Solution 2
- copy a working /etc/default/keyboard file to the directory that contains the Dockerfile
Add the following line to your Dockerfile before installing xdm or lightdm
COPY ./keyboard /etc/default/keyboard
Example keyboard file:
# Check /usr/share/doc/keyboard-configuration/README.Debian for
# documentation on what to do after having modified this file.
# The following variables describe your keyboard and can have the same
# values as the XkbModel, XkbLayout, XkbVariant and XkbOptions options
# in /etc/X11/xorg.conf.
XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT="intl"
XKBOPTIONS=""
# If you don't want to use the XKB layout on the console, you can
# specify an alternative keymap. Make sure it will be accessible
# before /usr is mounted.
# KMAP=/etc/console-setup/defkeymap.kmap.gz
BACKSPACE="guess"

I have the following Dockerfile:
# Pull from CentOS RPM Build Image FROM ubuntu # Update the image RUN apt-get update -y RUN apt-get install lightdm -yThe problem I have is when I'm building this container with
docker build -t dumbcontainer ., at some point I get an interactive menu for choosing a keyboard layout:Adding system user `lightdm' (UID 106) ...

Please select the country of origin for the keyboard of this computer. 1. Afghani 48. Irish 2. Albanian 49. Italian 3. Amharic 50. Japanese 4. Arabic 51. Japanese (PC-98xx Series) 5. Arabic (Morocco) 52. Kazakh ........I try putting an option, but the process just stalls at that point
Is there any way that I can choose an option interactively, or have docker pass an option when asked to do so?

ldg almost 8 yearsFYI - this does work (setting the TERM env) if you don't mind the interactive prompt (which you seem to be ok with). If you want something completely auto, you would need to see how to spec the keyboard option some other way. But also what @bmitch said. Vagrant or similar may be a better option. -
Vivek Shankar almost 7 yearsHad the same problem...these steps didn't work for me. Stuck with the same interactive menu. -
Nicu Stiurca about 6 yearsThank you!! I was only trying to install an X server in a Dockerfile, but the
DEBIAN_FRONTEND=noninteractivedid the trick just as well! -
Mohsin Bukhari over 4 years@arhuaco Hi, can you please share your Dockerfile for installing CUDA?
