Unable to locate package language-pack-en
apt-get, debian, docker, locale, ubuntu
Solution
If it's a debian image, you can add the following in your Dockerfile
RUN apt-get install -y locales locales-all
ENV LC_ALL en_US.UTF-8
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US.UTF-8
Problem
On my NodeJS server (running as docker image)... Dockerfile ``` FROM node:4.8-slim RUN apt-get update -y && \ apt-get install -yqq locales git ``` ...there is no english locale installed: ``` RUN locale -a ``` gives me ``` C C.UTF-8 POSIX ``` In my dockerfile I try to add the missing language ``` RUN apt-get install -y language-pack-en ``` But this gives me ``` Reading package lists... Building dependency tree... Reading state information... E: Unable to locate package language-pack-en ``` So how can I add the missing language pack? Update Using ``` sudo locale-gen en_US sudo locale-gen en_US.UTF-8 sudo update-locale ``` gives me this error: ``` perl: warning: Setting locale failed. perl: warning: Please check that your locale settings: LANGUAGE = "en_US:en", LC_ALL = "en_US.UTF-8", LANG = "en_US.UTF-8" are supported and installed on your system. perl: warning: Falling back to the standard locale ("C"). locale: Cannot set LC_CTYPE to default locale: No such file or directory locale: Cannot set LC_MESSAGES to default locale: No such file or directory locale: Cannot set LC_COLLATE to ``` default locale: No such file or directory
