apt-get upgrade fails on ubuntu:10.4 due to problems with libc6 preinst script about docker-brew-ubuntu-core

[tianon]

The official Ubuntu 10.04 server installer (ubuntu-12.04.4-server-amd64.iso) ...

So which is it that has the issue? 10.04, or 12.04? We don't actually support a 10.04 image in the main "ubuntu" images anymore, so I'm going to assume you mean 12.04 and go from there.

Here's what I get:

$ docker run -it --rm ubuntu:12.04 bash -c 'apt-get update && apt-get install -y libc6'

So maybe you just need to docker pull ubuntu to make sure you've got the latest updates to the image?

If you're looking for 10.04 specifically, you should check out the "ubuntu-debootstrap" image instead, which includes a 10.04 tag that will be supported until its EOL.

See also moby/moby#1724 for a nice long discussion about why you shouldn't apt-get upgrade in a container.

So which is it that has the issue? 10.04, or 12.04?

Oh, I'm so sorry. This was a stupid copy & paste error that even survived several proof readings.
Sorry for the inconvenience.

The issue is about 10.04. Both ISO and docker image had this version.
I'll check your advices and respond in more detail tomorrow when I'm back at work.

We don't actually support a 10.04 image in the main "ubuntu" images anymore

I did not know this. I thought all listed tags referred to supported images.
So this issue is obsolete, thanks for clarifying this.

I just tried the ubuntu-debootstrap image as you suggested and had no issues with libc6.
I had to add a mkdir /var/lib/apt/lists/partial step, though:

FROM ubuntu-debootstrap:10.04
RUN mkdir /var/lib/apt/lists/partial
RUN apt-get update
RUN apt-get install -y libc6

Thanks for your support.
