![运行 apt-get update(16.04)后未签名的存储库](https://linux22.com/image/1158948/%E8%BF%90%E8%A1%8C%20apt-get%20update%EF%BC%8816.04%EF%BC%89%E5%90%8E%E6%9C%AA%E7%AD%BE%E5%90%8D%E7%9A%84%E5%AD%98%E5%82%A8%E5%BA%93.png)
今天运行后apt-get update
拒绝更新存储库,因为它认为它们未签名。起初它只是给出At least one invalid signature was encountered
所有存储库的错误,但在尝试运行apt-get clean
、清理trusted.gpg.d等之后,它现在说存储库本身未签名。
我尝试了几个镜像,同样的错误也来自 PPA。(我已将它们从日志中删除)
我该如何修复这个问题?

答案1
我无意中在自己的文件系统中散布了 busybox 符号链接。这导致 apt-key 的 gpgv 方法失败,进而引发密钥错误。
