Thanks for reporting the issue. I tried reproducing the issue using the command:

docker build --no-cache -t df -rm .

The package supervisor was installed without problems, and the whole docker file was built without problems. I tested most of the commands from the README to check xpra still worked etc, as far as seeing the main menu in df. This was tested using Docker version 1.1.2, build d84a070.

Please try again using the --no-cache option, and if you are still getting problems let me know what version of docker you are using, and the command you are using to build.

Hi Ben,

I'm building with docker 1.3.2 and actually I used fig (www.fig.sh) to do the build part. I got it to build in the end by changing the redirect in the line which changes the /etc/apt/sources.list to append ( '>>' instead of '>' ).

Could well just have been something with no-cache as well, I'll have a go building it today maybe and see if using no-cache helps! On 24 Jan 2015 07:51, "Ben Cawkwell" notifications@github.com wrote:

By changing that line, you essentially rebuilt without using the cache, since that line sits at the top of the Dockerfile. The actual change you made should make little difference, as the way it currently behaves is to remove precise-updates and precise-security as sources.

Since you say it successfully built after you changed that line, I am going to close this issue since it was most likely caused by having an old cache of "apt-get update" that prevented installing supervisor. If I start to see this impact more people I might add "apt-get update" before each "apt-get install" command to reduce the chance of it happening, but that will make the built even slower than it is today so I would rather wait for proof that it is a common problem before changing it.

Feel free to report another issue if you get any more problems. I cannot promise I will have time to help right away but I will try.

Sound, that was probably it, I have a lot of stale ubuntu builds on the machine I did this on. On 24 Jan 2015 12:43, "Ben Cawkwell" notifications@github.com wrote:
