把以下代码全输一次，基本上解决了有时候杂乱的错误，当然不是说能解决所有。

rm -rf /var/lib/dpkg/lock-frontend;
rm -rf /var/lib/dpkg/lock;
sed -i 's/jessie/stretch/g' /etc/apt/sources.list;
apt upgrade -y;
apt update -y;
rm -rf /var/lib/dpkg/lock-frontend;
rm -rf /var/lib/dpkg/lock;
rm -rf /var/cache/apt/archives/lock;
rm -rf /var/cache/apt/archives/;
dpkg --configure -a;
mv /var/lib/dpkg/info /var/lib/dpkg/info.bk;
mkdir /var/lib/dpkg/info;
apt-get update -y;
apt-get install -f;
