答案1

您的命令行包含一 出现sudo，但也&&。在这种情况下sudo仅适用于前一个命令，而不适用于 之后的部分&&。sudo也添加到后一个命令。

sudo apt-get update && sudo apt-get upgrade -y

然而，至少还存在一个问题：

502  Connection timed out [IP: 2001:67c:1360:8001::21 80]

这意味着你应该检查网络连接。

通常，您应该逐个手动运行命令（即避免&&等-y）来诊断问题。

答案2

尝试以下命令：

sudo -i
apt-get clean
cd /var/lib/apt
mv lists lists.old
mkdir -p lists/partial
apt-get clean
apt-get update
