参照L大的帖子 安装时https://bbs.hassbian.com/thread-1858-1-1.html


在替换完源后

执行sudo apt-get update

遇到报错，网上搜下了，没找到靠谱的办法所以来次求救

[解决办法]：

sudo apt-get install debian-keyring

sudo apt-cache search -n dirmngr

sudo apt-get install dirmngr

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 8B48AD6246925553 （8B48AD6246925553 换成你的，出现几次不同的，本条命令执行几次）

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 7638D0442B90D010


sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EF0F382A1A7B6500


之后再执行一次命令 sudo apt-get update

villen

gpg --keyserver subkeys.pgp.net --recv 8B48AD6246925553
gpg --export --armor 8B48AD6246925553 | sudo apt-key add -

先运行这个 ，在update   试试看

由于没有公钥,无法验证 签名，重新添加了公钥
