如何在 Ubuntu 中恢复到旧版本的 libc6？

Question

我安装了 valgrind，它用一个略有不同的版本替换了我的 Ubuntu 12.04 系统上的 libc6，这破坏了我系统上的应用程序。我可以以某种方式恢复到 Ubuntu 5.1 版本吗？如果是这样，我在哪里可以找到它？

最大的问题可能是找到您之前安装的确切版本.deb，特别是如果您apt-get autoclean在两者之间安装的话。

一般来说，要安装特定版本，您会这样做

sudo apt-get install libc6=2.13-20ubuntu5.1

那么您可以使用以下命令将包裹标记为已持有：

echo "libc6 hold"|sudo dpkg --set-selections

以便后续更新不会自动更新它。您面临的问题是找到一个具有旧版本的镜像并使用它，或者找到.deb旧版本的镜像并用于dpkg -i ...手动安装它。

尝试locate libc6_2.13-20ubuntu5.1_amd64.deb查看是否有缓存副本。

然而，失败的程序有哪些症状呢？除了恢复到旧版本的libc6.
