我尝试反向移植Python 2.7.9从生动到可靠但是当 launchpad 构建这个包时出现构建错误。
我创建了我的反向移植：
backportpackage -d trusty -u ppa:splanquart/python http://archive.ubuntu.com/ubuntu/pool/main/p/python2.7/python2.7_2.7.9-1.dsc
我在 buildlog 底部遇到一个错误：
...

running python post-rtupdate hooks for python3.4...
Setting up lsb-release (4.1+Debian11ubuntu6) ...

我该如何解决这个问题？
我搜索了降级 gcc 和 dpkg-dev 依赖项版本的方法，但没有成功。为此，我清除了所有内容，然后...我通过以下方式下载软件包：
backportpackage -d trusty --dont-sign -w . http://archive.ubuntu.com/ubuntu/pool/main/p/python2.7/python2.7_2.7.9-1.dsc
我更改了版本构建依赖在python2.7_2.7.9-1~ubuntu14.04.1.dsc：
Build-Depends: debhelper (>= 5), dpkg-dev (>= 1.17.5), gcc (>= 4:4.8.2), quilt, autoconf, autotools-dev, lsb-release, sharutils, libreadline-dev, libtinfo-dev, libncursesw5-dev (>= 5.3), tk-dev, blt-dev (>= 2.4z), libssl-dev, zlib1g-dev, libbz2-dev, libexpat1-dev, libbluetooth-dev [linux-any], locales [!armel !avr32 !hppa !ia64 !mipsel], libsqlite3-dev, libffi-dev (>= 3.0.5) [!or1k !avr32], libgpm2 [linux-any], mime-support, netbase, net-tools, bzip2, libdb-dev (<< 1:6.0), libgdbm-dev, python:any, help2man, xvfb, xauth
在我通过以下方式上传到启动板后：
backportpackage -u ppa:splanquart/python python2.7_2.7.9-1~ubuntu14.04.1.dsc
但我也遇到了同样的错误：
...
running python post-rtupdate hooks for python3.4...

答案1
ppa:fkrull/deadsnakes-python2.7是最新版本的python2.7
sudo add-apt-repository ppa:fkrull/deadsnakes-python2.7
sudo apt-get update
sudo apt-get upgrade
它将升级 Python 到 2.7.10
答案2
看起来您的dpkg-dev和gcc包对于构建过程来说还不够新。
尝试：
sudo apt-get update
sudo apt-get install gcc4.9
sudo apt-get upgrade dpkg-dev
然后再次执行，backportpackage看看是否有所改善。由于构建过程似乎正在寻找 gcc 4.9，因此第二个命令
