由于 libstdc++6 不正确而导致的问题

由于 libstdc++6 不正确而导致的问题

当我这样做时,sudo apt-get -f install我得到

Preparing to unpack .../libstdc++6_8.1.0-5ubuntu1~14.04_amd64.deb ...
Unpacking libstdc++6:amd64 (8.1.0-5ubuntu1~14.04) over (5.4.0-6ubuntu1~16.04.10) ...

我使用的是 Ubuntu 14.04.5

这可能是因为与 libstdc++ 冲突。 (当我尝试安装 adobe acrobat 时发生)我如何/在哪里找到正确版本的 libstdc++6 以及如何卸载损坏的版本?

的输出apt-cache policy libstdc++6:i386

libstdc++6:i386:

(我在上面写****时已经截取了完整的IP地址)

$ dpkg --print-foreign-architectures is

的输出dpkg -l libstdc++6

输出grep -v "#" /etc/apt/sources.list

deb http://mirror**/ubuntu/ xenial main restricted
deb-src http://mirror**/ubuntu/ xenial main restricted

等等。
如果我手动编辑此文件并将 xenial 更改为 trusty ,问题会得到解决吗(运行apt-get-clean无助于解决此问题)

当我跑步时sudo apt-get install --reinstall libstdc++6:i386,我得到:

Reading package lists... Done

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 libstdc++-5-dev : Depends: libstdc++6 (>= 5.5.0-12ubuntu1~14.04) but 5.4.0-6ubuntu1~16.04.10 is to be installed
 libstdc++6 : Depends: gcc-5-base (= 5.4.0-6ubuntu1~16.04.10) but 5.5.0-12ubuntu1~14.04 is to be installed
              Breaks: libreoffice-core (<= 1:4.4.4~rc3-0ubuntu1) but 1:4.2.8-0ubuntu5.1 is to be installed
              Breaks: libstdc++6:i386 (!= 5.4.0-6ubuntu1~16.04.10) but 8.1.0-5ubuntu1~14.04 is to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

apt-get -f install由于与线程开头提到的相同原因,我无法运行。让我知道可以做什么。

答案1

看起来你的/etc/apt/sources.list情况很糟糕。您不知何故最终在 Trusty (14.04) 系统上启用了 Xenial (16.04) 存储库。这显然会导致像这样奇怪的包冲突。

只需修复/清理您的存储库配置,运行apt-get clean,一切就应该重新开始工作。

答案2

使用此命令删除较新的 (16.04) libstdc++6 软件包

sudo dpkg --remove --force-depends libstdc++6:amd64

从此处的软件包存储库下载 trusy (14.04) 的 libstdc++6 版本 https://launchpad.net/ubuntu/trusty/amd64/libstdc++6/4.8.2-19ubuntu1

解压包并将下载包中的 3 个文件复制到相应位置

sudo cp libstdc++.so.6.0.19 /usr/lib/x86_64-linux-gnu/

sudo cp -P libstdc++.so.6 /usr/lib/x86_64-linux-gnu/

sudo cp -P libstdc++6 /usr/share/doc/

apt-get 现在应该可以工作,重新安装 libstdc++6 以修复依赖项

sudo apt-get install --reinstall libstdc++6 sudo apt-get -f install

您现在应该恢复正常了
