debian/ubuntu: There is no public key available for the following key IDs

教程分享 04-04 3869

Linux虽然比Windows的安全系数要高，但是经常更新还是个好习惯（至少近期就爆出了不少关于SSL的安全漏洞值得大家重视！），但是在Ubuntu和Debian下运行apt-get update刷新更新源的时候却经常遇到“There is no public key available for the following key IDs”的问题，具体表现为以下错误提示：

W:There is no public key available for the following key IDs: 3B4FE6ACC0B21F32,
W:There is no public key available for the following key IDs: 3B4FE6ACC0B21F32,

直接的解决方案：

apt-get install debian-keyring debian-archive-keyring

apt-key update

完了！
