我有一个 Debian wheezy 服务器，用于使用pbuilder和构建软件包。我目前可以为 Debian 、和git-buildpackage构建软件包。sidwheezysqueeze
我想使用同一台服务器为 Ubuntu 发行版构建软件包。我曾尝试通过在 中创建一个可信任的配置文件来执行此操作/etc/pbuilder/trusty，但我从 debootstrap 收到错误：
-> Invoking pbuilder
forking: pbuilder create --configfile /etc/pbuilder/trusty --buildplace /var/cache/pbuilder/base-trusty.cow --mirror http://debian.stanford.edu/ubuntu --distribution trusty --no-targz --extrapackages cowdancer
W: /root/.pbuilderrc does not exist
I: Running in no-targz mode
I: Distribution is trusty.

forking: rm -rf /var/cache/pbuilder/base-trusty.cow
以下是输出apt-key list：

也许有人知道正确的配置可以让我做到这一点。或者我应该放弃并基于 Ubuntu 本身构建一个单独的构建服务器？

问题是 debootstrap 不使用/etc/apt/trusted.gpg或中的本地密钥环/etc/apt/trusted.gpg.d/，而仅使用 下的密钥环/usr/share/keyrings/。
从 Debian 8 Jessie 开始，你可以简单地安装（官方 Debian）软件包ubuntu-存档-密钥环它应该可以解决你的问题。
在早期的 Debian 版本中，您可以让 pbuilder 传递--keyring=/etc/apt/trusted.gpg给 debootstrap，因为该文件中已经有正确的密钥。--debootstrapopts --keyring=/etc/apt/trusted.gpg根据其手册页，添加到 pbuilder 调用应该可以做到这一点。
