背景：尝试安装 AVG，搞砸了，不得不手动从 /bin 等中删除文件等
现在，当我运行 apt-get update、apt-install 或 apt 时，我会得到以下返回

从这种情况发生的频率来看，AVG 一定在我的 apt 参考 sources.list 中。查看后，没有与 AVG 相关的内容。还有其他 apt 可从中提取的列表吗？我该如何阻止此错误再次出现？
答案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
还建议对已删除的文件进行更全面的检查。您必须安装 debsums 并按如下方式运行它：
sudo apt-get install debsums
sudo debsums_init
sudo debsums -a -c -s
然后通过如下命令手动重新安装提到的包
sudo apt-get install --reinstall htop。
