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. 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.

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):

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.
As an optional step, we recommend that you also install our
