Some files are missing from new package installs on bionic containers #101

Closed mike10004 closed 4 years ago

In containers based on the bionic-curl and bionic-scm images, for some new packages installed with apt, not all files in the package are present after installation. In particular, some files under /usr/share/doc and /usr/share/man are missing.

Steps to reproduce: 

$ docker run --rm -it buildpack-deps:bionic-curl /bin/bash -l

root@73b619bd6c3e:/# apt update > /dev/null 2> /dev/null
root@73b619bd6c3e:/# apt install hello

root@73b619bd6c3e:/# ls /usr/share/doc/hello/NEWS.gz 
ls: cannot access '/usr/share/doc/hello/NEWS.gz': No such file or directory
root@73b619bd6c3e:/# ls /usr/share/man/man1/hello.1.gz
ls: cannot access '/usr/share/man/man1/hello.1.gz': No such file or directory

The output of dpkg --verify and ls shows that the files are missing.

This behavior is not exhibited on xenial-curl or buster-curl.

Any idea what could be causing this or how to address it?

This was an intentional upstream Ubuntu change for Bionic+ Docker images: https://github.com/tianon/docker-brew-ubuntu-core/issues/122

Thank you for the quick and relevant response -- googling what I was seeing was bringing up all the wrong leads.

For anyone stumbling on this, you can add the line

RUN rm /etc/dpkg/dpkg.cfg.d/excludes

to your dockerfile to make dpkg behave normally and unpack files in /usr/share/doc and /usr/share/man.
