由于未满足的依赖关系，Apt无法工作。

Question

我知道这个问题在ask ubuntu上讨论过很多次了，但是我仍然没有用我所遇到的解决方案来解决它。

sudo apt-get purge calibre的输出是：

sudo: unable to resolve host ubuntu
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:
 click : Depends: python3-click-package (= 0.4.43+16.04.20160203-0ubuntu3) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

任何其他apt命令都将导致“未满足的依赖项”错误。如何在添加PPA之后解决未满足的依赖关系？中提到的方法：sudo apt-get -f install或sudo dpkg --configure -a或去除ppa没有帮助。

有人能帮我把我的乌本图带回来吗？

Answer 1

检查您的/etc/hosts，看看是否有正确的本地地址和私有ip地址(如果您没有在这个系统上运行dhcp )。

但是如果您正在运行dhcp，那么

sudo /usr/sbin/dhclient eth0
 ## eth0 or the name of your interface

在系统开始下载之前，它需要先解决自身问题。希望你能在这一点上有一个休息的机会：

sudo apt-get autoclean ## discards any saved pkgs and start off with fresh ones
sudo dkpg -r calibre
sudo dkpg -r python3-click-package
sudo apt-get remove --purge calibre
sudo apt-get remove --purge python3-click-package
sudo apt-get dist-upgrade

sudo apt-get build-dep python3-click-package
sudo apt-get install python3-click-package
sudo apt-get build-dep calbire
sudo apt-get install calbire

最后，这可能是过火和不必要的，但我发现，在某些情况下，它是有帮助的，当我有困难的工程系统与apt-get存储库，但是，谁知道。另外，“肯定比抱歉”没有坏处。

sudo dpkg --configure -a
sudo dpkg-reconfigure -a

我很少发现自己处于下一个“最后手段”的位置，但是，每次都以老式的方式去做这件事，这确实对我有好处。

sudo aptitude 

然后按g获取依赖项并扫描其他依赖项的其他需求，然后按u更新系统，最后；ctrl-c (还是ctrl-x？)退出智能并重新启动。

希望你能找到你的宝宝Ubuntu从现在开始寻找你。;)
