如何修复 apt-get “未满足的依赖关系”错误？

每当我尝试使用 安装任何东西时apt-get，都会收到错误消息：

apt-get install abinit
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:
 libpng12-0 : Breaks: libpng12-0:i386 (!= 1.2.54-1ubuntu1) but 1.2.54-1ubuntu1.1 is to be installed
 libpng12-0:i386 : Breaks: libpng12-0 (!= 1.2.54-1ubuntu1.1) but 1.2.54-1ubuntu1 is to be installed
 libpng12-dev : Depends: libpng12-0 (= 1.2.54-1ubuntu1.1) but 1.2.54-1ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

我该如何修复这个问题？如果我尝试建议的apt-get -f install命令，它会抱怨：

Preparing to unpack .../libpng12-0_1.2.54-1ubuntu1.1_amd64.deb ...
Unpacking libpng12-0:amd64 (1.2.54-1ubuntu1.1) over (1.2.54-1ubuntu1) ...
dpkg: error processing archive /var/cache/apt/archives/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb (--unpack):

Errors were encountered while processing:
 /var/cache/apt/archives/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

聪明人会怎么做？

答案1

这句话似乎很重要：

trying to overwrite shared '/usr/share/doc/libpng12-0/changelog.Debian.gz'

一篇较早的文章 (打包过程中的 changelog.Debian.gz 文件是什么？）建议你可以安全地删除changelog.Debian.gz（当然你也可以用 进行备份sudo cp /usr/share/doc/libpng12-0/changelog.Debian.gz ~/Desktop/changelog.Debian.gz）

因此在这种情况下，我将首先删除更改日志，然后进行更新。

通常，当我遇到错误时apt，apt-get我也会运行它sudo apt-get clean来进行一些基本的整理。

答案2

使用 重新配置包数据库sudo dpkg --configure -a。然后重试。如果这仍然不起作用，请尝试删除 libpng。
