如何在 ubuntu 中获得 sid pbuilder

Question

在将软件包发布到 Debian（然后将它们同步到 Ubuntu）之前，我需要在 sid chroot 中测试它们，但在干净的 14.04 系统上出现此错误：

$ sudo DIST=sid ARCH=i386 pbuilder create
[sudo] password for u: 
I: Distribution is unstable.
I: Current time: Mon Mar 17 09:37:53 EDT 2014
I: pbuilder-time-stamp: 1395063473
I: Building the build environment
I: running debootstrap
/usr/sbin/debootstrap
I: Retrieving Release 
I: Retrieving Release.gpg 
I: Checking Release signature
E: Release signed by unknown key (key id 8B48AD6246925553)
E: debootstrap failed
W: Aborting with an error
I: cleaning the build env 
I: removing directory /var/cache/pbuilder/build//8688 and its subdirectories

我必须安装什么类型的密钥才能避免此类故障？

Answer 1

为了修复它，我必须安装：

sudo apt-get install debian-archive-keyring

然后创建 chroot

sudo DIST=sid ARCH=i386 pbuilder create --debootstrapopts \
--keyring=/usr/share/keyrings/debian-archive-keyring.gpg
