处理存档 /var/cache/apt/archives/libc6_2.27-3ubuntu1_amd64.deb 时出错

Question

当我运行 sudo apt-get -f install 时，它显示 dpkg：错误处理。我也跑过sudo dpkg -i --force-overwrite /var/cache/apt/archives/libc6_2.27-3ubuntu1_amd64.deb

sudo dpkg -i --force-overwrite /var/cache/apt/archives/libc6_2.27-

Answer 1

对我有用的是这两个命令：

sudo fuser -kv /var/cache/debconf/config.dat

进而

sudo apt --fix-broken install

fusionr 命令是一个非常智能的 UNIX 实用程序，用于查找哪个进程正在使用文件、目录或套接字。它还提供有关拥有该进程的用户和访问类型的信息。fusion 工具显示使用指定文件或文件系统的每个进程的进程 ID (PID)。

• kflag 用于终止进程 ( --kill)
• v标志用于详细且清晰的输出 ( --verbose)
