xdm not available

[zwischenzugs]

Hi,

Not a defect, but this might help others:

I get this error when building the image:

root@lp01728:/space/docker# docker build -t zwischenzugs/docker-desktop git://github.com/rogaha/docker-desktop.git Step 1 : FROM ubuntu:12.10 ---> b750fe79269d Step 2 : MAINTAINER Roberto G.

However, when I run the build by hand it seems to work.

Solution was to add no-cache:

root@lp01728:/space/docker# docker build -no-cache=true /space/git/docker-desktop

Hi @zwischenzugs,

Thanks for sharing this issue. I'll try to replicate it and I'll test your solution.

Hi @zwischenzugs,

I was not able to replicate it using the latest version of docker. I'm going to close this issue, but feel free to open it again if you have this type of problem again!

Thanks
