E: Sub-process /usr/bin/dpkg returned an error code (1)

我该如何解决这个问题？

Answer 1

啊哈，是的。Debian包管理的古老的“22条军规”情况。归根结底就是依赖于py3compile作为libpython3.x包的一部分，而这个包也提供了py3compile；这是行不通的。

我也被这个问题刺痛了，无法让py3compile再次工作，因为我也删除了整个/usr//local/lib/python3*目录。

一旦完成，Debian包管理工具中的任何东西都不能帮助您返回到工作的Python3环境。你必须做肉丸手术。

在Debian中重建Python3需要三件关键的事情：

python二进制恢复py3compile脚本(对于大多数用户来说，您已经拥有this)

• Restoring libpython3.7

• Restoring
• py3compile

可以从另一个正常运行的Debian主机/系统重新复制/usr/local/lib目录。但这一次，我将详细介绍所讨论的损坏主机中的步骤(就好像您没有另一台工作主机一样)。

第1步-下载软件包

下载受影响的Debian包：

cd /tmp
apt-get download libpython3.7-minimal
apt-get download python3.7-minimal
apt-get download python3-minimal # (this is important)
apt-get download libpython3.7-stdlib
apt-get download python3.7

第2步-清理

清理旧东西

rm -rf /usr[/local]/lib/python3.7*
rm -rf /usr[/local]/bin/python3.7*
update-alternatives --remove python3 /usr[/local]/bin/python3.7
hash -r  # removes cached python3 binary path

第3步-从包中提取文件

让我们提取缺少的py3compile

cd /tmp
dpkg-deb -x python3-minimal_3.7.3-1_amd64.deb missing
dpkg-deb -x python3.7-minimal_3.7.3-2_amd64.deb missing
dpkg-deb -x libpython3.7-minimal_3.7.3-2_amd64.deb missing
dpkg-deb -x libpython3.7-stdlib_3.7.3-2_amd64.deb missing
dpkg-deb -x python3.7_3.7.3-2_amd64.deb missing

第三步

在根文件系统上手动安装

cd /tmp/missing
ls -lR /tmp/missing  # if you are curious about overwriting your HD
sudo cp -rpfv /tmp/missing/*  /

第4步-验证

启动Python3

python3
Python 3.7.3 (default, Apr  3 2019, 05:39:12) 
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

测试导入和显示版本

>>> import sys
>>> print(sys.version_info)
sys.version_info(major=3, minor=7, micro=3, releaselevel='final', serial=0)
>>>
>>> quit()

第五步--清理一下自己

rm -rf /tmp/missing

第6步-通过Debian APT正式重新安装Python

dpkg -s -a  | grep  reinstreq
# Any listing also needs to be reinstalled along with python3
apt-get install --reinstall python3

最有可能的是，你得到了许多处于"reinstreq“状态的包。

apt-get autoclean
apt-get autoremove
# (MANY PACKAGES FAILED TO BE INSTALLED)

在这一点上，您将不得不手动重新安装apt-get autoremove列出的每一个...

apt-get install --fix-broken --reinstall <list-of-many-failed-packages>

最后一步-重新安装受影响的半状态Debian包

让我猜猜，你得到了以下错误：

E: Internal Error, No file name for XXXXXX

我要告诉你，你的/etc/apt/sources.list中可能有一段时间有一个更新的Debian版本，它变得一团糟(坏了)，并从sources.list文件中删除了新的版本(努力恢复到一个“稳定”的版本)：这对我来说不是一个不可恢复的事情，只是你在那里稍微动了一下Debian包数据库……相当粗鲁。

最后一步的解决需要通过重新安装几乎所有的东西来恢复和稳定Debian包管理数据库。我将在稍后详细介绍它，但是下面的链接是here。

Answer 2

py3compile:未找到

py3compile命令是似乎已损坏的python3-minimal包的一部分。

要解决此问题，请尝试以下操作：

• 通过以下方式更正存在已损坏依赖关系的系统：

sudo apt-通过以下方式获取所有未打包但未配置的-f install

• Reconfigure包：

sudo dpkg --配置-a

• 如果上面没有帮助，请尝试通过以下方法重新安装python3-minimal包：

sudo apt install -f --reinstall python3-minimal

或者运行：

apt-get下载python3 3-minimal sudo dpkg -i *python3*.deb sudo apt install -f

或者通过以下方式下载.pkg file from kernel.org并从该文件安装：

sudo dpkg -i python3-minimal_*.deb

然后确保py3compile和py3clean命令是可运行的，并且可以从PATH变量访问它们。

Answer 3

尽管/usr/bin/中有py3compile和py3clean，但我的Lubunutu16.10shell (tcsh)一直抱怨py3compile不在那里。在经历了几个小时的挫折之后，我发现pycompile中的第一行是：

! /usr/bin/env python

或者类似的东西，在我的系统上引用Python2.7。使用以下命令将其更改为指向Python 3：

! /usr/local/bin/python3

突然让py3compile变得可见了！

原来，当py3compile引用Python2.7时，外壳程序说py3compile不存在，即使它在它的路径中，或者直接使用"/usr/bin/py3compile“执行。shell甚至没有抱怨Python版本或其他任何东西，它只是声称py3compile本身并不存在！

我陷入这种混乱是因为我想删除并重新安装Python3.5，在这样做时，我发现仍然有一个Python3，然后我发现它来自一个python-minimal，我试图删除并重新安装它。即使我在网上和每个包管理器上尝试了所有我能找到的东西，python-minimal也不会重新安装。他们都会抱怨py3compile失踪了。现在我发现了py3compile的这个修复。
