Gitian LXC build fails to find 'base-lucid-amd64'

[dcf]

I tried doing the Gitian build for the first time, so this ticket might be because I'm doing something wrong. It appears to have successfully build "tor-linux for lucid i386", but then failed at "tor-linux for lucid amd64".

What I did to set up the Ubuntu build VM:

http://releases.ubuntu.com/precise/ubuntu-12.04.3-server-amd64.iso

qemu-img create -f qcow2 ubuntu-12.04-server-amd64-gitian.hda 50G
kvm -k en-us -hda ubuntu-12.04-server-amd64-gitian.hda -m 2G -smp 4 -cdrom ubuntu-12.04.3-server-amd64.iso

Here's what I see at the end of the build output.

Kathy Brade and I encountered the same problem. The real failure occurs during VM creation: the 32-bit VM is created OK but appears to fail, which causes creation of the 64-bit VM to be skipped, which eventually leads to the build failure. We have a patch that we are testing now and I will attach it here once I know that it works.

[mcs]

proposed fix (set LXC_ARCH and LXC_SUITE when using LXC)

Our build is still going but the attached patch fixes the VM creation problem.

This got probably fixed during rebasing gitian-builder (#10104 for the general ticket and #10558 for the one setting LXC_ARCH and LXC_SUITE).

I just finished an LXC build without incident. (Even matched the KVM build for 3.5.3.)
