apt安装中的问题：“子进程返回错误代码”

Question

背景:尝试安装AVG，搞砸了，不得不手动删除/bin文件等等。

现在，当我运行apt-get update、apt-install或apt时，我得到以下返回：

从这个频率来判断，AVG必须在我的apt参考sources.list中。看了看，没有任何与AVG有关的东西。还有另一份名单是从哪来的？如何防止此错误再次出现？

Answer 1

您必须手动创建此目录

sudo mkdir -p /opt/avg/av

然后继续安装

sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get upgrade

还建议对删除的文件进行更全面的检查。您必须安装借方并按以下方式运行：

sudo apt-get install debsums
sudo debsums_init
sudo debsums -a -c -s

然后通过以下命令手动重新安装所述的包

sudo apt-get install --reinstall htop。
