答案1
首先使用以下命令修复多行错误：
sudo rm /etc/apt/sources.list.d/xenial-partner.list*
或者如果上述命令在末尾没有星号而引发错误：
sudo rm /etc/apt/sources.list.d/xenial-partner.list
然后，要么重启电脑，要么简单地等一会儿，如果你刚刚启动了它，可能是你激活了无人值守更新，并且此过程正在锁定管理目录。如果这仍然不起作用，你可以使用以下命令（注意，仅当情况在等待片刻后仍未自行修复时才使用此命令，如@RoVo的评论)：
sudo rm -vf /var/lib/apt/lists/*
选项-v用于显示详细输出，选项-f用于强制执行命令，这里将它们合并为一个。请记住在从计算机中删除实际列表后-vf重新运行。sudo apt update
为了修复 CD-Rom 错误，您需要编辑文件中的第一行/多行，并在提到 cdrom 的行前面/etc/apt/sources.list添加：#
deb cdrom://Ubuntu 16.04.1 LTS Xenial Xerus - Release amd64 (20160719) xenial
deb-src cdrom://Ubuntu 16.04.1 LTS Xenial Xerus - Release amd64 (20160719) xenial
进入
# deb cdrom://Ubuntu 16.04.1 LTS Xenial Xerus - Release amd64 (20160719) xenial
# deb-src cdrom://Ubuntu 16.04.1 LTS Xenial Xerus - Release amd64 (20160719) xenial
