From: Alexandru Avadanii Date: Tue, 8 Mar 2016 00:44:05 +0100 Subject: [PATCH] Prevent common cross-debootstrap newaliases issue. While building target images for a different arch (using qemu-user-static), the following issue prevents the succesful image build: newaliases: fatal: inet_addr_local[getifaddrs]: getifaddrs: Address family not supported by protocol For more information, see [1].
