答案1

尝试以下命令

sudo apt-get clean
sudo mv /var/lib/apt/lists /tmp
sudo mkdir -p /var/lib/apt/lists/partial
sudo apt-get clean
sudo apt-get update

答案2

似乎获取软件包列表的 URL 有误。请检查/etc/apt/sources.list地址是否http://us.archive.ubuntu.com/ubuntu/;对我来说,好像您的条目sources.list缺少 ubuntu/ 部分。

答案3

/tmp如果您的目录已满,您也会收到此错误。
