由于未满足依赖关系，apt-get update 无法正常工作

Question 1

看来 Python 安装已损坏..尝试重新安装python3-minimal

sudo apt-get install --reinstall python3-minimal

现在您可以sudo apt-get install --fix-broken再次运行，然后apt-get update..如果失败请告诉我们。

Question 2

我也遇到过这个问题 - 在我使用 Raspbian 从 wheezy 升级到 jessie 时。软件包python3-minimal处于不良状态，调用py3clean和py3compile命令时 debconf 的 prerm 和 postinst 钩子脚本失败。

直接运行命令时确实py3clean出现问题：

-bash: /usr/bin/py3clean: /usr/bin/python3: bad interpreter: No such file or directory

尝试重新安装该python3-minimal包导致错误：

$ sudo apt-get install --reinstall python3-minimal
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 idle3 : Depends: idle-python3.4 but it is not going to be installed
 python3 : Depends: python3.4 (>= 3.4.2-0) but it is not going to be installed
           Depends: libpython3-stdlib (= 3.4.2-2) but it is not going to be installed
           Depends: dh-python but it is not going to be installed
 python3-minimal : Depends: python3.4-minimal (>= 3.4.2-0) but it is not going to be installed
 python3-numpy : Depends: python3.4 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

建议的apt-get -f install命令仍然无效。

最终，我通过注释掉与 py3clean 相关的行解决了该问题，如下/var/lib/dpkg/info/debconf.prerm所示：

if which py3clean >/dev/null 2>&1; then
       py3clean -p debconf 
fi

然后我必须注释掉 py3compile 行/var/lib/dpkg/info/debconf.postinst：

if which py3compile >/dev/null 2>&1; then
       py3compile -p debconf 
fi

这让我成功运行

sudo apt-get -f install

此时，我可以干净地重新安装该软件包，这也方便地删除不再需要的上述脚本定制。

sudo apt-get install --reinstall debconf

Question 3

仍然：：

/var/lib/dpkg/info/debconf.prerm: 24: /var/lib/dpkg/info/debconf.prerm: py3clean: 未找到

虚拟 /usr/local/bin/py3clean 包含 ::

/bin/sh #!/bin/sh 复制代码

回显“py3clean 虚拟”

然后sudo apt-get -f install工作
