(sorry about the non-threaded copy - odd attachments messing up my email here...) I mentioned on irc - can you check what your env proxy settings are - it looks like the osbuilder scripts pass on (lower case) http_proxy etc.: https://github.com/kata-containers/osbuilder/blob/a12618811dd715c2d4438ce3c6... Soo, if you are maybe using HTTP_PROXY, in your env, maybe this does not work? You could run that script (or whichever script you are running) with 'set -x', to see if those docker command line parameters make it through OK. (and, don't forget, this is a public list - don't post your actual proxy settings here - not the IP addresses/machine names at least ;-) Graham ----------- Hi Eric, I'll give your feedback in the morning (It's a little late in PRC). --Thanks Changcheng From: Ernst, Eric Sent: Wednesday, June 6, 2018 8:59 PM To: Hunt, James O <james.o.hunt@intel.com<mailto:james.o.hunt@intel.com>> Cc: Liu, Changcheng <changcheng.liu@intel.com<mailto:changcheng.liu@intel.com>>; kata-dev@lists.katacontainers.io<mailto:kata-dev@lists.katacontainers.io> Subject: Re: [kata-dev] osbuilder/rootfs build with docker on native ubuntu host Can you see if you can start an Ubuntu container and run apt-get update within the container? It sounds like connectivity to me as well. Docker needs proxy settings separately for inside the container connectivity.

Could you try re-running and if that doesn't work, raising an issue with the output of `sudo kata-collect-data.sh` pasted into the github issue? - https://github.com/kata-containers/osbuilder/issues/new Cheers, James 2018-06-06 13:12 GMT+01:00 Liu, Changcheng <changcheng.liu@intel.com<mailto:changcheng.liu@intel.com>>: Hi all, I fail to build rootfs on ubuntu host after following the "rootfs-builder/README.md<http://rootfs-builder/README.md>" guide.
