我使用以下命令将 OpenVZ VPS 从较旧的 Ubuntu 版本升级到 12.04LTS do-release-upgrade。从那时起，我的所有apt-get运行看起来都像这样：
$ sudo apt-get upgrade

我确信 OpenVZ 环境的某些方面导致了此问题，可能是simfs /以及 中缺少任何磁盘 ( hd_) /dev。但是，尽管我花了几个小时阅读所有我能找到的有关该/usr/sbin/grub-probe: error: cannot find a device for / (is /dev mounted?).错误的资料，但我仍然遇到这个问题。
更糟糕的是，我可以从应该是干净的备份中恢复。但我宁愿不这样做，因为这意味着需要进行一些与 BOINC 相关的棘手步骤来与附加项目重新同步。
答案1
我的解决方案是：
~# apt-get remove linux-image linux-image-generic
~# mv /var/lib/dpkg/info/linux-image-3.2.0-35-generic.* /tmp/
~# dpkg --remove --force-remove-reinstreq linux-image-3.2.0-35-generic
最后两个步骤按照“在 Ubuntu/Debian 中手动删除损坏的软件包“。
apt不再抱怨dpkg安装过程中的配置错误，这很好，因为今天我发现apt-get install甚至不再安装任何东西了；错误dpkg在任何安装工作发生之前就中止了该过程。但现在一切都正常了。
