apt-get 升级 libc 失败

今天早上我想升级 unetbootin 包。一切都很顺利，直到出现这个错误。

所以我确实尝试了建议apt-get -f install

但这导致了以下错误

我已经尝试过 apt-get clean apt-get update && apt-get upgrade

但这也无济于事。同样的错误正在发生。我有点不确定我是否敢于重新启动。我该如何解决这个问题？

首先，将/lib/x86_64-linux-gnu 这些文件移动到/root：libc-2.17.so libdl-2.17.so libm-2.17.so libpthread-2.17.so librt-2.17.so

进入目录/lib/x86_64-linux-gnu并将文件复制到的命令/root，

sudo -s
cd /lib/x86_64-linux-gnu
cp libc-2.17.so /root
cp libdl-2.17.so /root
cp libm-2.17.so /root
cp libpthread-2.17.so /root
cp librt-2.17.so /root

然后你需要使用预定义的命令启动 bash LD_PRELOAD：

LD_PRELOAD=/root/libc-2.17.so:/root/libdl-2.17.so:/root/libm-2.17.so:/root/libpthread-2.17.so:/root/librt-2.17.so bash

删除/lib/x86_64-linux-gnu目录中文件的命令，

rm libc-2.17.so
rm libdl-2.17.so
rm libm-2.17.so
rm libpthread-2.17.so
rm librt-2.17.so

之后dist-upgrade或fix-missing package将会起作用：

apt-get -f install

或者

apt-get -f dist-upgrade

感谢 Avinash Raj！

我按照你的方法解决了这个问题。但对你的方法做了一些小改动：

  1. sudo

    cd /lib/x86_64-linux-gnu cp libc-2.17.so /root cp libdl-2.17.so /root cp libm-2.17.so /root cp libpthread-2.17.so /root cp librt-2.17.so /root cp ld-2.17.so /root/

mkdir /root/i386

和cd /lib/i386-linux-gnu cp libc-2.17.so /root/i386 cp libdl-2.17.so /root/i386 cp libm-2.17.so /root/i386 cp libpthread-2.17.so /root/i386 cp librt-2.17.so /root/i386 cp ld-2.17.so /root/i386

  1. 预加载： LD_PRELOAD=/root/libc-2.17.so:/root/libdl-2.17.so:/root/libm-2.17.so:/root/libpthread-2.17.so:/root/librt-2.17.so bash

  2. 删除库： cd /lib/i386-linux-gnu rm libc-2.17.so rm libdl-2.17.so rm libm-2.17.so rm libpthread-2.17.so rm librt-2.17.so rm ld-2.17.so

cd /lib/x86_64-linux-gnu/ rm libc-2.17.so rm libdl-2.17.so rm libm-2.17.so rm libpthread-2.17.so rm librt-2.17.so rm ld-2.17.so

  1. apt-get -f install 执行此命令时遇到错误“找不到文件 lib6”，我通过以下方式恢复它 dpkg -i /var/cache/apt/archives/*.deb ：dpkg --configure -a

  2. 然后我就可以进行 dist-upgrade。 apt-get dist-upgrade
