This bug affects gitian-builder when used with lxc. Gitian-builder is the reproducible build tools used by Bitcoin Core and other projects. The relevant gitian-builder bug is https://github.com/devrandom/gitian- builder/issues/95.
I have confirmed this bug with a 15.04 chroot. As you can see from the gitian-builder issue, GitHub user @droark also experienced the issue when using 15.04. The relevant output from my 15.04 chroot: root@debian:~/gitian-builder# make-clean-vm --suite trusty --arch amd64 sudo: unable to resolve host debian lxc-execute: conf.c: instantiate_veth: 2660 failed to attach 'vethU5U6JE' to the bridge 'br0': Operation not permitted lxc-execute: conf.c: lxc_create_network: 2943 failed to create netdev lxc-execute: start.c: lxc_spawn: 914 failed to create the network lxc-execute: start.c: __lxc_start: 1164 failed to spawn 'gitian' -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1452601 Title: vivid container's networking.service fails on boot with signal=PIPE Status in lxc package in Ubuntu: Confirmed Bug description: When starting a Vivid container, it fails to get an IP address. It believes networking.service was successful, but actually it dies with SIGPIPE. Restarting networking.service gets an IP, as expected. Starting networking used to work with pre-vivid containers. I'm reasonably sure this fails 100% of the time.
