sub-process /usr/bin/dpkg ret

这个错误通常表示正在运行的 dpkg 进程被意外终止，可能是由于意外的计算机关闭或其他中断引起的。解决这个问题的一种方法是清除 dpkg 锁文件并重新运行 dpkg 命令。你可以尝试以下步骤来解决这个问题：

1. 打开终端并以管理员身份运行以下命令，以确保没有其他 dpkg 进程正在运行：

   sudo lsof /var/lib/dpkg/lock
   sudo lsof /var/lib/apt/lists/lock

2. 如果上述命令返回结果，请使用以下命令杀死相关的进程：

   sudo kill <进程ID>

3. 删除 dpkg 锁文件：

   sudo rm /var/lib/dpkg/lock
   sudo rm /var/cache/apt/archives/lock

4. 更新软件包列表并修复可能损坏的软件包：

   sudo apt-get update
   sudo dpkg --configure -a

完成这些步骤后，你应该能够重新运行 dpkg 命令而不再遇到此错误。
