Apt

Debian is a Linux distribution that's composed entirely of free and open-source software. I’ve always been wondering how Docker works in this regards, and whether I should either make as many “RUN apt-get install” commands as possible, or if I should instead try to use as few RUN commands as possible, as these increases the number of layers (?). So for example: RUN apt-get update && apt-get install -y python-qt4 python-pyside python-pip python3-pip python3. FROM ubuntu:20.04 RUN apt update # We directly answer the questions asked using the printf statement RUN printf 'y 1 1n' apt install nodejs RUN apt install -y npm Here we do our docker build: docker build -t mynpm. Here is the version check to verify its success: docker run -it mynpm npm -v The output I get as a result is: 6.14.4.

Kitware APT Repository. This is Kitware, Inc.' S third-party APT repository, which we use for hosting our own Ubuntu packages, such as CMake. We currently support Ubuntu 16.04, 18.04, and 20.04 on our repository. Mac os x lion 10.7 dmg downloadg download. On newest image 0.9.19, if I run any apt-get command, I received the following red warning line: debconf: delaying package configuration, since apt-utils is not installed Minimal example: FROM phusion/baseimage:0.9.19 # Use baseimage-doc.

We currently support Ubuntu 16.04, 18.04, and 20.04 on our repository. The 16.04 and 18.04 repositories support x86 (32-bit and 64-bit), and the 20.04 repository supports x86 (32-bit and 64-bit) and ARM (32-bit and 64-bit).

To add the repository to your installation, do the following in order:

  1. If you are using a minimal Ubuntu image or a Docker image, you may need to install the following packages:

  2. Obtain a copy of our signing key:

  3. Add the repository to your sources list and update.

    For Ubuntu Focal Fossa (20.04):

    For Ubuntu Bionic Beaver (18.04):

    For Ubuntu Xenial Xerus (16.04):

  4. As an optional step, if you would like to subscribe to release candidates in addition to production releases, you can add our release candidate repository to your sources.

    For Ubuntu Focal Fossa (20.04):

    For Ubuntu Bionic Beaver (18.04):

    For Ubuntu Xenial Xerus (16.04):

    Note that if you add the release candidate repository, you will still need to add the main repository as well, as the release candidate repository does not provide production releases on its own.

  5. As an optional step, we recommend that you also install our kitware-archive-keyring package to ensure that your keyring stays up to date as we rotate our keys. Do the following:

Now you can install any package from our APT repository. As an example, try installing the cmake package:
