上周 ubuntu 要求安装一些更新。安装后出现了一系列问题（之前一切都运行正常……）现在我无法使用和apt-get命令，因为这些“缺少依赖项”……
这些问题似乎与 、 和 有关man-db。openssh-server我r-base唯一知道的是，RUbuntu 尝试安装的新版本（通过包管理器）是测试版。无论如何，我没想到会有这样的自动建议……这就是我得到的

抱歉转储了这么多代码，但我基本上陷入了困境。由于上述原因，任何 apt-get 操作都被阻止。这简直太荒谬了，因为我没有要求进行任何更新，我只是确认了 Ubuntu 所说的“重要更新”。
答案1
我通过以下方式解决了问题
sudo rm -f /etc/apt/sources.list.d/*
sudo dpkg -i /var/cache/apt/archives/*.deb
sudo dpkg --configure -a
答案2
错误报告的一部分清楚地表明，
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
表示/var/cache/debconf/config.dat已被另一个进程锁定，从而阻止当前进程配置包。因此请等待该进程释放/var/cache/debconf/config.dat此资源。如果没有其他进程正在使用此资源，只需重新启动即可解决您的问题。
