Trying to create an OS (icehouse) image for a centos 6.5 nova server. Running the latest diskimage-builder on CentOS 7with the heat-config element fails:

Any idea how to fix this? It seems like the issue is with a package that's being downloaded as part of the process. Not something I have installed already on the machine on which I'm running diskimage-builder.

I'm not able to reproduce the problem - my build on a CentOS 7 vm completed fine.

It looks like you may be behind a proxy - is it possible that it cached an old index or something that would be causing issues?

[Mark Horstman (mah042)]

Yes. I am behind a proxy. But it is not a caching proxy. Did you find something in the log that showed it had downloaded the incorrect version?

I can't imagine that it matters but the CentOS7 guest on which I'm running diskimage-builder is just a generic KVM guest built using the attached kickstart file.

[Mark Horstman (mah042)]

I thought it might have something to do with the 'sudo su' not carrying the proxy environment variables forward, but that's not it. I've confirmed they're set in the 'sudo su' environment, but it still fails the same way. Could I be getting a bad mirror? How would I tell?

I also got the same error message trying to create a disk image, diskimage-builder/bin/disk-image-create vm with heat-config-*.
Yes, I am behind a proxy with http_proxy and https_proxy set properly - I can run apt-get update, wget or curl to external site without any issue. What is so special about oslo.i18n that it could not find any downloads while it has no problem with other packages? Please let us know if anyone finds a fix for this. Thank you.

I'm also seeing this error running behind a proxy. It worked fine last week so its not a proxy configuration issue.

[Eshe Pickett (eshe-n-pickett)]

Running with Ubuntu, I too ran into this issue and was able to get around it by doing the following in my environment:

PIP_PROXY=<your_proxy>
PIP_ALLOW_EXTERNAL=true

[Eshe Pickett (eshe-n-pickett)]

I ran into this again, and also set:

export PIP_DOWNLOAD_CACHE=/opt/pip/cache

This has been very consistent for me.
